T&D India (November 2017) - Swithchgear & Control Panels

Very recently, Power Grid Corporation of India Ltd announced that it has formed an equal
joint venture with the Uttar Pradesh state power transmission utility. This joint venture
will build intrastate power transmission lines in the northern state. PGCIL had formed a similar
joint venture in Bihar, which has recently started operations. Kerala State Electricity Board is
also seeking the involvement of PGCIL in its intrastate power transmission network. KSEB is
evaluating several options to this effect, and among them is a proposal for a joint venture.
It is time that state power transmission utilities seek the active involvement of PGCIL in ramp-
ing up their intrastate networks. Over the years, power transmission technology has become
increasingly sophisticated and it will be very helpful for state utilities to seek the assistance of
PGCIL. In terms of technology and practices, PGCIL is ahead of the curve. It has to its credit
building 1,200kV lines, which is the highest voltage level in the world. Besides, PGCIL has
completed projects in topographically challenging conditions both in India and outside.
PGCIL, as consultant, has already been helping state governments in their power transmission
endeavours. However, the joint venture modality is a better option as it will elicit more “involve-
ment” from PGCIL. As an equity partner, PGCIL will be a shareholder in the project risk, unlike
when it is merely a consultant.
The formation of a joint venture could be a cumbersome process due to procedural formalities
but it is worth the effort. State governments should actively pursue the joint venture route with
PCGIL, ensuring that discussions progress rapidly till the formation of the joint venture. Odisha,
it is learnt, had also planned a JV with PGCIL, on the lines of Bihar, but the initial discussions
did not progress till fruition.
With the involvement of PGCIL as a joint venture partner, state governments can be sure that
they are on firm footing in their quest for establishing a technically and commercially efficient
intrastate grid.

T&D News
ower Grid Corporation
of India (PGCIL) has
successfully completed and
charged the 220kV single-circuit
Leh-Khalsti line, which is part of the
longer 220kV single-circuit Srinagar
(Alusteng)-Leh transmission line.
Along with the Leh-Khalsti line
spanning 63 km, two 220/66kV GIS
substations—at Leh and Khalsti—
have also been commissioned.
This is also the first time in India
that a 220kV substation has been
built at an altitude of over 11,500ft, a
government release observed.
The Srinagar-Leh transmission
scheme was awarded to PGCIL, due
to the project’s strategic importance
and technical complexities. The
foundation stone of the project was
laid by Prime Minister Narendra
Modi in August 2014.
Theprojectaimstoreliablytransmit
electricity to the topographically-
challenged Ladakh region of Jammu
& Kashmir. With the Leh-Khalsti line
now commissioned, Ladakh region
can receive electricity from the 45-
mw Nimoo-Bazgo hydropower plant
situated in Leh district. This NHPC-
owned plant, designed to generate
239 million kwh of electricity per
year, was commissioned in October
2013. The Nimoo-Bazgo plant will
feed its entire power generation to
Jammu & Kashmir.
The remaining part of the Srinagar-
Leh transmission scheme, which is
mainly the Khalsti-Kargil-Drass-
Srinagar (Alusteng) section, is under
construction. Once completed, the
Ladakh region will receive reliable
electricity supply directly from the
Northern Grid.
The extent of isolation
The erstwhile Leh district was
bifurcated into Leh and Kargil in
1979. Ladakh, covering around
60,000 sqkm, broadly refers to the
region included by both Leh and
Kargil districts. Ladakh covers
around 70 per cent of the total
geographical area of Jammu &
Kashmir. The difficult terrain of
Ladakh has left this region isolated,
with very low density of population.
According to the 2011 Census, the
density of population of Leh district,
which has an area of around 45,000
sqkm, is only 3 persons per sqkm.
The comparable metric for Kargil is
around 10 persons per sqkm.
Currently, there is no electric
connectivity between Ladakh and
the national grid. Establishing this
connectivity is the main objective
of the Srinagar-Leh transmission
scheme, which includes 375 km of
single-circuit transmission line at
220kV from Srinagar (Alusteng) to
Leh, via Kargil and four 220/66kV
GIS substations at Drass, Kargil,
Leh and Khalsti. The entire project
is estimated to cost around Rs.1,800
crore, 95 per cent of which will be
spent by the Central government.
Ladakh region currently gets
its electricity from local micro-
hydropower projects aggregating
some 14 mw, and diesel generators
worth 12 mw. The energy shortage
in the Ladakh region is as high as
95 per cent. Once the entire Leh-
Srinagar transmission line is fully
commissioned,Ladakhregionshould
get reliable power of about 100-150
mw, from the Northern Grid. n
P
One Grid, One Price seen on IEX
the day-ahead power market at IEX for the first time ever witnessed the convergence of
market prices all over India for all hours in a day for the entire month of October 2017,
realizing the “One Grid-One Price” aspiration, a statement from IEX said.
The average market clearing price (MCP) for the month at Rs.4.08 per unit was almost
same as in September 2017and was 66 per cent higher than the Rs.2.46 per unit in
October 2016.
A total volume of 4,079 MU (million units) was cleared in October 2017, almost the
same as that of September 2017 and about 13 per cent more than in October last year.
With average daily sell bids at 169 million units against buy bids at 179 million units,
the market largely remained in deficit mode. The total sell bids during the month were
5,248 million units and the total buy bids were 5,535 million units.
The spot power price reflected the demand-supply dynamics in the market and
the supply side saw several constraints like coal shortages, reduced hydro and wind
generation affecting the market, the statement observed.

concerns about the use of SF6.
Please tell us more.
Though SF6 gas is known to be
a greenhouse gas with global
warming potential, it is still used for
high voltage and medium voltage
switchgear because of its excellent
quenching and insulation abilities
and also to reduce overall losses in

network management and energy
management with an exhaustive
range of solutions under each pillar.
Discuss in brief how digitization
can help bring energy efficiency
in power distribution. How can
digitization help lower energy
bills?
We believe that the digitisation of
the power grid in the country will
ensure improved optimization of
resources and will ultimately reduce
the cost of electricity in India. This
can lower our ATC losses, both
technical and commercial losses
to an impressive extent. With more
digitisation, we will be able to
reduce more losses.
Modern day technological
advancements such as the Internet
of Things (IoT), analytics and cloud
are indispensable parts of any kind
of digital transformation and can
provide a lucrative platform for
digitising the grid. A connected
smart grid on these lines will
unfalteringly enable consistent
and real time monitoring of energy
distribution and transmission assets,
among other things. The energy
which is actually being produced
but not consumed, are getting into
the network and the average cost of
energyiscertaintocomedown.Today,
one is paying for the inefficiencies
also. Less inefficiencies will mean
improved costs. Thus, it is evident
that digitization will improve the
distribution network in the power
sector.
Schneider Electric’s open IoT-
enabled framework EcoStruxure is
designed to ensure higher efficiency
in grid operations, optimal asset
management and facilitate an
overall shift towards digitisation of
power distribution in the country
to achieve the Centre’s goal of
providing reliable 24x7 Power for All.
The company is presently working
with various state discoms to provide
digital technologies for the grid.
The EcoStruxure™ Grid platform
helps distribution system operators
(DSOs), manage the complexity
arising from digitalisation of
utilities. It is an open, interoperable,
IoT-enabled system architecture
and platform targeted at several
verticals, including the grid market
and DSOs. n

What is the basic difference between
AIS (air insulated switchgear) and
GIS (gas insulated switchgear)?
While GIS uses sulphur hexafluoride
(SF6) gas, which is five times heavier
than air, AIS is based on air insulation
in a metal clad system. Installing
GIS is faster and easier since GIS
systems are significantly smaller and
lighter as compared to AIS.
GIS systems are also easier to
maintain on a regular basis owing
to their front access. They generally
need to be inspected every four
years or so depending on the specific
manufacturer recommendations of
the device. GIS drives need to be
re-greased after about 20 years. AIS
systems, on the other hand, have to
be inspected every one or two years.
Talking in terms of the cost of
ownership, the upfront costs of GIS
and AIS must be weighed against the
lifelong maintenance these devices
demand. GIS units tend to cost 10-
40 per cent more than AIS devices.
The minimum lifespan of switchgear
systems is 30 years.
What technical advantages that GIS
offers over AIS?
GIS systems save a lot of space. GIS
substations take up only 10 per cent
of the space that a conventional (air-
insulated) substation occupies. SF6
has superior dielectric properties
when used at moderate pressure for
phase-to-phaseandphase-to-ground
insulation. Arc flashes are rare in
GIS as all the interior elements are
insulated.
What advantages does GIS offer to
EPC contractors, over AIS?
The cost of GIS may be more, but it
offers a higher return on investment.
Hartek Group is a
specialist in providing
EPC solutions for
substations and
transmission lines up
to 400kV. Recently, the
group landed its first
order for a
gas-insulated
switchgear (GIS)
substation in Haryana.
In this exclusive
exchange with
TD India,
Simarpreet Singh
tells us how GIS-
based substations are
technically superior
to their air insulated
counterparts, not just
in terms of technology
but also from the
perspective of EPC
contractors.

GIS scores over AIS both in terms of
upkeep and installation time. GIS
systems are not only much faster
and simpler to install, they are also
quite easier to maintain. But we,
at the Hartek Group, believe that
no matter what the technology is,
the success of a substation project
hinges on finer aspects of design,
engineering and installation with
high quality standards being the
cardinal principle.
GISusesSF6(sulphurhexafluoride)
that is considered environment-
unfriendly. What is your view?
So as to ensure environmental and
personal safety, we should make
it a point to adopt certain system
design standards which minimise
pollution, like hermetically-sealed
gas compartments and provisions for
gas recycling and disposal. Effective
handling policies, both during
maintenance and final disposal,
can go a long way in addressing the
issue.
Are there any challenges that
EPC contractors face during the
execution of projects involving
GIS?
One of the major challenges before
us is looking for ways to reduce
the cost of constructing new GIS
facilities and retrofitting them as
technology evolves. But to be able
to do that without compromising on
reliability and overall quality poses
an even bigger challenge. Executing
GIS substations in difficult urban
locations can also be a formidable
task.
Hartek recently forayed in the GIS
substation EPC space. Tell us more.
Hartek Group recently bagged
its first-ever GIS project of 132kV
from the Haryana Vidyut Prasaran
Nigam Ltd (HVPNL), which will
be constructed in Jhajjar. We have
been targeting GIS-based projects
for the past two-three years as we
feel the need to move towards newer
technologies to create a smart power
infrastructure for the country.
Does GIS have any specific
(technical) advantage when it
comes to TD infrastructure for
solar power plants?
From an EPC contractor’s point of
view, executing GIS substations
for solar plants can save a lot of
time, which is of utmost importance
when it comes to renewable energy
projects. Otherwise, GIS offers by
and large the same advantages
for both solar and conventional
substation projects.
What is India’s level of self-reliance
when it comes to key equipment
used in GIS-based substations?
India is fairly self-reliant in GIS-
based substation technologies. With
GIS-based substations expected to
come up on a large scale in the near
future, Indian companies are ready to
cash in on the emerging trend. Many
of these companies have already tied
up with foreign multinationals to
make their presence felt.
Apart from multinationals
operating in India, do you see
homegrown companies supplying
GIS equipment?
Absolutely! Though domestic
manufacturers in the GIS equipment
market face stiff competition from
foreign multinationals, they have
demonstrated time and again that
they are second to none in terms
of quality and reliability. India
has the resources and capability
to manufacture complex products
and come up with technological
innovations. Indian manufacturers
should come up with indigenous
technological advancements
by emulating MNCs who have
developed world-class products
over the years, by investing heavily
in RD. The “Make in India”
campaign should emphasize on
technological applications and
encourage homegrown companies
to take the lead in GIS technology
and practices. n

The growing importance of
gas-insulated switchgear
T
he switchgear industry is
among the major industries
serving the Indian power
sector. In coming days the switchgear
industry is expected to show healthy
growth. The requirement of power
in the upcoming industries and the
massive rural electrification drive
is poised to keep the switchgear
industry very busy. In this industry,
technology is the basic resource.
It is very natural that most of the
multinational companies are major
players in the switchgear industry as
theyhaveaccesstosourcetechnology.
However, in the years to come, many
Indian companies are expected
to upgrade their technologies and
develop switchgear products to serve
the rapidly-growing power industry.
Before moving to gas-insulated
switchgear, it is worthwhile to
understand the overall structure and
dynamics of the switchgear industry.
Switchgear products are broadly
distributed across four ranges, and
the market trends of each group
depend on various criteria like
product criticality, technology, safety,
price and type of users.
Low voltage
Product criticality: In this range
voltage is low and current is high.
Hence product is not so critical.
Technology: Mostly air insulated
technology is used. This technology
is very old and conventional hence
many more designs are available.
People are also very familiar with the
product.
Safety: As the product is not so
critical, people give relatively less
importance to the safety aspect.
Price: There is huge requirement
and hence there is correspondingly
large volume of production. This also
results in tremendous competition.
Most manufacturers belong to the
small and medium enterprise (SME)
category. Big companies, including
multinationals, cater to the low-
voltage switchgear segment, largely
to keep their presence alive.
Users: Users include utilities,
industries and others. The user base
is large because these products
cater to the last end of the power
distribution value chain.
Medium Voltage
Product criticality: As voltage
increases, so does the product
criticality.
Technology: In this range, air-
insulatedswitchgearwastraditionally
the only option. However, nowadays
gas-insulated switchgear (GIS) has
emerged as the latest technology.
Most customers prefer GIS for
automation and remote operation.
Safety: As the product is critical,
more importance is attached to the
safety aspect.
Price: All utilities and industries
using high-voltage (HV) equipment
are the main customers of this
product category. Competition in
terms of pricing has increased as
many local players have developed
products.
Users: As discussed, users are
utilities and industries that use high-
voltage equipment.
High and Extra-high voltage
Product criticality: As the voltage
is high and extra-high, product
criticality is greatly enhanced.
Technology: In this range,
air insulated and gas insulated
switchgear are the only options. In
open air substation, air insulated
switchgear is preferred and for
indoor substations, users go in for
GIS. In this range, technology is
very important and most of the
manufacturers are major companies.
There are no small and medium scale
manufacturers in this range.
Safety: Switchgear products in this
range command high importance to
safety.
Price: All utilities and industries
are the main customers. Price
pressure has somewhat increased as
many local players have developed
products.
Users: Users are utilities and
industries that use HV equipment.
Gas Insulated Switchgear
Gas insulated switchgear (GIS) is
very compact form of switchgear.
Because of the use of SF6 (sodium

the rapidly-growing
power industry.

hexafluoride) insulation, the size of
the switchgear reduces drastically.
This product is normally used
in medium and high voltage
application.
GIS is more safe, compact and
maintenance-freeascomparedtoAIS.
The longevity of GIS is also higher
than AIS. In GIS most of the current-
carrying and live components are
sealed in SF6. Constant atmospheric
conditions in the sealed tank improve
the performance of switchgear.
In GIS, design is the most
critical aspect. Most multinational
companies have developed this
product in their global technology
centres. In India very few companies
have developed GIS designs.
Designing of GIS or technology of
GIS is not available easily. While
designing few important points,
designer should look at critical
aspects like leak-proof joints,
over-pressure sustaining capacity,
maintenance-free mechanisms
and overall performance of all
components to sustain guarantee of
15-20 years in field.
The challenges in GIS
manufacturing can be overcome by
taking utmost care at three stages:
Design: Selection of proper raw
material is very important. Sealing
material is very important because
in India temperature variation band
is very wide. Tank design to sustain
the internal arc is very important
and critical. The selection of the
material should be based with a
clear understanding of the required
mechanical strength.
Manufacturing: perfection in
assembly and on component level is
required. Multistage inspection is
required.
Erection and commissioning:
All procedures given by the
manufacturers need to be followed
meticulously.
Space is the biggest constrain
in India. Other functional criteria
like safety, maintenance and
downtime are the key parameters
for distribution. All utilities and
industries are looking for safe and
maintenance-free products. It has
been proved that after installing the
GIS cost of maintenance and cost
of production loss due no power
has dropped drastically. Whereever
uninterrupted power supply is
required, GIS can be used.
Type testing of the GIS is very
expensive task. Testing facilities for
some of the tests are not available in
India. For switchgear manufacturers,
it is very difficult to undertake some
part of the testing in India and some
outside India. Hence most of the
manufacturers prefer testing the
entire equipment at international
laboratories. Product certification
from international laboratory helps
to capture the market outside India
as well.
Process control is the main function
in the manufacturing of GIS.
Small mistake in the component or
assembly affects the performance of
the entire GIS. At every level of the
manufacturing process, inspection
is required. Testing for gas leakage
requires huge investment.
In summary, some of the major
shortcomings in GIS development
in India are lack of designing
ability and manufacturing skills;
and inadequacies of type-testing
laboratories and local testing
facilities.
China is a very attractive market
for GIS and its components. In
many utilities, China-make products
are not approved. However, many
manufacturers are using auxiliary
components for GIS from China. n

W
hen we talk of a scientific
mind in the AC electricity
supply system, one cannot
but admire the Siberian-American
inventor Nikola Tesla. What drove
him was the following context from
where he came: “The desire that
guides me in all I do is the desire to
harness the forces of nature to the
service of mankind.”
Harnessing power, whether it
is hydro, wind, solar or any other
source, require switchboards in
standard and customized designs,
to make this happen. It is here
that protection, measurement,
automation, monitoring and
management of electricity takes
place.
This article attempts to explore the
way this is done presently and could
be done going forward.

Onvarioustrips,abroadtocountries
like Singapore, Sri Lanka, Dubai
and Denmark, I reckoned that to
overcome the above disadvantages,
I had to shift from a welded design
to a modular design of switchboard
manufacturing. Thus, was launched
MODUTECourmodularswitchboard
enclosure systems in the year 2000.
These modular panels helped Load
Controls overcome all the above
challenges and helped grow the
business steadily since then.
Today, we have many switchgear
companies launching their own
modular switchboard designs in
India and partnering with local panel
builders to offer a technologically
smarter and type-tested system to
electrical installations. For example,
we have LT with their TI genres,
Schneider with Blockset and Prisma
models, ABB with their R2K panel
offerings, Siemens with their Seipan
versions, Legrand with their XL
Cube standard, and so on.
Customers are slowly preferring
to go the way of these standardized
modular designs of panels since
the type test certification of IEC
61439 calls for 13 tests and these
are to be done with specific make
of switchgear in the panels. Further,

end-users felt the need for
flexibility in forms of construction,
types of switchgear and desired
certainty in compliance to
specifications related to dust,
liquid and vermin protection,
painting quality, bus bar systems
to handle both short circuit
currents as well as temperature
rise, mechanical robustness and
so on. All these offer the end user,
peace of mind and hence modular
design in switchboards is gaining
acceptability and finding its place in
tender specifications as mandatory.
Other benefits of the modular
designed switchboards are that even
after the switchboards are installed
at site, should there be changes in
converting 2 modules into one big
one or vice versa, this would be
possible, unlike in welded designs.
Moreover, most designs permit for
hinged door reversibility from LHS
to RHS and vice versa, a feature
which is again absent in welded
versions.
What the standardized designs
open up for the switchboard industry
is the possibility of franchisee or
alliance partnership associations
across geographies. With a
centralized mechanical enclosure
manufacturing unit, one could have
the flat pack kits dispatched to
various cities wherein the electrical
value addition and customization
can take place with all the scalable
features supporting the engagement.

In India apart from MODUTEC
we also have BCH from Faridabad

be long before the switchboard
industry consolidates to wipe out the
conventional welded players and
replace them with these advanced

In general, what are the practical
difficulties while testing GIS or
its components, when compared
with conventional (air-insulated)
switchgear?
Gas-insulated switchgear (GIS) is
often used in applications where
space is limited and the current
carrying parts are embedded in
SF6 gas. On-site testing of GIS is
therefore often a challenge as the
conductor is only accessible via
grounding switches.
When measuring operating times
on GIS with grounding on both
sides, common test methods don’t
deliver reliable results due to the
low-ohm ground connections that
run parallel to the circuit breaker. For
this reason, timing measurements
are often conducted with insulated
grounding switches where a shunt
can be removed to interrupt the
low-ohmic parallel measuring path.
Yet this carries the risk of capacitive
coupling from adjacent components
or switchbay sections on the non-
grounded conductor part. Therefore,
on-site testing using these methods
is often impossible or prohibited in
many cases.
Tell us briefly about the new
“Current Sensor Measurement
(CSM)” method and how it
is different from the earlier/
conventional methods.
The circuit breaker test system
CIBANO500offersanew,alternative
method for measuring operating
times in GIS – called Current Sensor
Measurement (CSM) method. This
new method allows the operating
times to be determined accurately
while the GIS is grounded on both
sides.
The ground connections (shunt)
on the grounding switch don’t
need to be removed and additional
components don’t need to be
installed. A current sensor just
needs to be wrapped around the
shunt on the grounding switch.
Since these sensors have a flexible
design and can easily be installed on
a multitude of different grounding
switches, they are ideal for on-site
applications in GIS installations.
Please explain the role of CSM
while testing the operation of a
circuit breaker, especially when it is
part of a gas-insulated switchgear.
Generally, the circuit breaker test
system CIBANO 500 can test all
performance-, motion-, as well as
coil and motor-related parameters
of GIS circuit breakers with the
same test setup. The connection
to the circuit breaker only needs
to be done once. With the optional
CB MC2 modules, this can save a
lot of testing time, as conventional
measuring devices require this
wiring to be done at least twice.
When a timing measurement on
a GIS breaker must be performed
Andreas Nenning has
a degree in automation
engineering and
mechatronics from the
University of Applied
Science in Dornbirn,
Austria. He has been
the product manager for
OMICRON’s new circuit
breaker test set CIBANO
500, since September
2013. In this exchange,
Nenning explains in
depth how CIBANO 500
and OMICRON’s current
sensor measurement
(CSM) method help
overcome practical
difficulties in performing
on-site tests on gas-
insulated switchgear.

CIBANO 500 offers a new
method for GIS testing
— Andreas Nenning, Product Manager,

interview Focus: Switchgear Control Panels
GIS testing with CIBANO 500 and
CSM Method

with both sides grounded, CIBANO
500 offers the possibility to use the
new current sensor measurement
method (CSM).
How does the CSM work in
conjunction with CIBANO 500
when it comes to testing of GIS?
The CSM method measures the
operating time via an inductive
current change measurement using
the parallel ground connection or
the circuit breaker, while the GIS
remains grounded on both sides. In
order to do this, the circuit breaker
is connected to CIBANO 500 via the
CB MC2 accessory. The CB MC2
has a constant current source (e.g.,
IDC = 200 A) and a measurement
channel for the current sensor. The
sensor is laid around the ground
connection of the grounding switch.
The current change that is measured
through the ground connection
or the circuit breaker is then used
to determine the switch response
times. The circuit breaker remains
grounded on both sides throughout
the entire measurement.
Has the CSM-CIBANO 500
technique been launched in India?
The CIBANO 500 circuit breaker test
system and the new CSM method
are available in India. This product
was featured at the recent Indian
User Meeting during 1-3 November
2017, in Delhi.
Apart from the CSM and CIBANO
500, what are the innovative testing
solutions by Omicron OMICRON
for testing of GIS?
After timing measurements or high
residual currents with transient
DC components, there may be
some residual magnetism left over
in the GIS’s current transformer.
CIBANO 500 also features the “CT
Demagnetization” function, which
quickly and easily demagnetizes
the current transformer after contact
resistance or timing measurements.
OMICRON also offers a mobile,
scalable high-voltage source
and a reliable partial discharge
measurement system. This
combination allows fast and easy
on-site PD measurements on gas-
insulated switchgear in the ultra-
high frequency range.
Additionally, OMICRON offers a
solutiontoperformvoltagewithstand
tests on GIS in accordance with the
IEC 62271-203 standard. It provides
test voltages of up to 235kV on GIS
with nominal voltages of 145kV. n

Mega power transmission
projects facing RoW constraints
Lead story
Venugopal Pillai

O
ver half of the
interregional power
transmission projects
awarded under the tariff-
based competitive bidding (TBCB)
mechanism are facing right-of-way
challenges, a study by TD India
suggests. The basic data for the study
was obtained from official reports
released by Central Electricity
Authority.
In its report dated October 2017,
which normally has data up to
September 30, 2017, the CEA report
observed that there were 20 TBCB-
mode power transmission projects
under construction, which included
partially commissioned projects. Out
of these, 13 projects were affected
by either right-of-way challenges
or were experiencing delays with
respect to forest clearance. In many
cases, this was adversely affecting
the commissioning schedule. It
should be also noted that many of
the projects not affected by RoW
constraints were actually in the
survey stage, and had not yet begun
physical activity.
One project where serious RoW
constraints persist is the transmission
scheme for evacuation of power
from various IPPs in Nagapattinam/
Cuddalore area of Tamil Nadu.
The project is being developed by
PowergridNagapattinam-Madhugiri
Transmission Ltd, a wholly-owned
subsidiary of Power Grid Corporation
of India Ltd (PGCIL). The project
involves two components—a
765kV double-circuit line from
Nagapattinam Pooling Station to
Salem;anda765kVsingle-circuitline
from Salem to Madhugiri. While the
first component was commissioned
in October 2016, the second has been
seriously affected by RoW issues. As
againstthescheduledcommissioning
date of December 2015, the project
is anticipated to complete only by
March 2018. Severe RoW constraints
are being faced in the Karnataka
portion where 130km of the line
lies. Work has come to a standstill in
Ramnagar and Tumkur districts for
several months now. Matters have
come to such a pass that the Prime

Minister, during his visit to the state
in August this year, has directed the
Karnataka Chief Secretary to resolve
the RoW issue in two months.
One more notable example is the
400kV Samba-Amargarh double-
circuit line of 562 ckm, which is
taking shape in Jammu Kashmir.
This line is part of the Northern
Region System Strengthening
Scheme (NRSS)-XXIX being
developed by Sterlite Power. Right-
of-way issues have cropped up in
Jammu, Badgam and Baramulla.
Besides, overall unrest in Jammu
Kashmir has hampered activity in
general. Help has been sought from
District Collectors of these districts
to expedite the process.
There is another case where right
of way has been hampered, not by
private land, but due to the presence
of coal mines. The project in question
is the Eastern Region System
Strengthening Scheme (ERSS)-
XIX, developed by Adani Group.
The transmission project aims to
provide evacuation infrastructure
to NTPC’s upcoming 1,980-mw
North Karanpura thermal power
project in Jharkhand. For a 63-ckm
stretch that passes over the North
Karanpura coalfield, there was a
rather unexpected impediment.
Central Coalfields Ltd and Central
Mine Planning Design Institute
disallowed construction on the
route suggested by the bid process
coordinator. The revised alignment,
as suggested by CCL and CMPDI,
would mean tremendous escalation
in both cost and completion time.
During a meeting held in May
2017, both CCL and CMPDI agreed
November 201727TD India
to reevaluate the original route, if
the developer gave an undertaking
that the proposed transmission line
would be dismantled after 35 years,
which is the concession period.
While the developer has submitted
an undertaking to this effect, the
final resolution of the matter is still
awaited.
Right of way is also becoming a
concernarisingfrompoliticalreasons
as seen in the case of a transmission
scheme that aims to transmit
electricity to India from upcoming
hydropower projects in Bhutan. One
segment of this transmission scheme
is the 232-ckm 400kV Alipurduar-
Siliguri line, which is facing RoW
concerns. At several locations along
the alignment, landowners are
demanding very high compensation.
It is alleged that the demand for
unreasonable compensation is a
politically motivated move. The
developer, a subsidiary of Kalpataru
Power Transmission, is understood to
be taking up rigorous negotiations
with landowners.
Overall Status
As of October 2017, a total of 37
interstate transmission projects
were awarded under the tariff-based
competitive bidding route. Out of
these 13 were completed while 20
were under construction or partially
complete. The remaining four are in
distress.Oneproject,officiallyknown
as “Transmission system associated
with IPPs of Vemagiri Area (Package
A)” has been officially terminated
by Central Electricity Regulatory
Commission, as it found the project
unnecessary. The project was won
Power Grid Corporation of India,
and was to be implemented through
its 100 per cent subsidiary Powergrid
Vemagiri Transmission Ltd.
In the case of one project, the
developer (transmission service
provider) has requested for
cancellationoftheproject,apparently
due to financial constraints. The
developer in this case is DGEN

Transmission Company Ltd, which is
a 100 per cent subsidiary of Spanish
entity Instalciones Abensa SA.
Reliance Power Transmission
Company Ltd, belonging to the Anil
Ambani group, has invoked the “force
majeure” clause and is seeking tariff
increase to the tune of 90 per cent
in two projects. Both of these were
awarded way back in 2010, and
there has been no physical work on
both the projects. While one scheme
relates to transmission evacuation
related to the North Karanpura and
other generation projects in north
India, the other is associated with
the Talcher project in Odisha.
The players
The interstate TBCB power
transmission market is dominated
by Power Grid Corporation of India
and Sterlite Power that together
have over half of the number of
projects awarded till October 2017
(see table). Essel Infra, Adani Power
and Kalpataru Power Transmission
represent the emerging players in
the business. Apart from these, there
are a few other companies but they
are not active currently. Reliance
Power Transmission has won two
projects but both of them are under
litigation.
Instalaciones Inabensa, a Spanish
infrastructure company, is the only
foreign entity that is present in the
interstate TBCB power transmission
market. However, the company has
sought closure of its only project, due
to financial concerns. Concerns were
expressed in Parliament recently
about the potential involvement of
Chinese companies in the power
transmission market, especially
as developers. Though Chinese
companies have submitted bids,
none have won a project so far.
Larsen Toubro has commissioned
its sole project (Kudgi transmission
scheme) and has not been bidding
actively in recent times. Much
is the same with Kolkata-based
Techno Electric Engineering. It is
interesting to note that in January
2011, an equal consortium of BS
Ltd (then known as BS Transcomm
Ltd), Patel Engineering and Simplex
Infrastructures won the Raichur-
Sholapur transmission project. The
project was significant because
it was one of the transmission
lines for connecting the southern
grid to rest of India, resulting in a
truly synchronous national grid.
The Raichur-Sholapur project was
important also because it was for the
first time that a consortium approach
was followed whilst bidding for
power transmission projects.
Interestingly, this has remained the
only case of its kind till date, at least
in the context of interstate power
transmission lines awarded under
the TBCB route. n

As we understand the mega
ELECRAMA 2018 was completely
sold out in three months flat. Was
such a huge response anticipated?
Yes, ELECRAMA space was sold out
completely within three months of its
launch. We are extremely delighted
with the response we received for
ELECRAMA 2018. Due to huge
demand for the first we had to add
additionalspaceasrequestsforspace
were pouring in from everywhere.
Was it anticipated? This year we
were looking at a different approach
to promote country’s biggest
electrical exhibition. We created a
thorough communication plan to
engage with the past exhibitors and
agencies and promised them an
experience they never had before.
This communication worked for us
and so did the ideology of taking
ELECRAMA 2018 to next level.
Please discuss ELECRAMA 2018 in
terms of number of exhibitors and
number of countries participating.
The mega event will have more than
1,100 exhibitors showcasing their
products and services and visitors
from more than 100 countries will be
participating in it. Most important,
visitor footfalls anticipated are
more than 2,50,000. The five-day
event will have various pavilions
of interest. There will be a power
pavilion, railway pavilion and also
an “E-Tech Next” to showcase the
technology of tomorrow.
This year’s ELECRAMA focuses
on the paradigm shift from the earlier
TD in electricity space to electric
vehicles, Internet of Things (IoT),
storage solutions and renewable
energy.
The mega power TD
show, ELECRAMA
2018, organized by
industry body IEEMA is
scheduled to be held in
March 2018. We have
Vijay Karia discussing
the various contours of
this grand event. Karia
is encouraged with the
stupendous response
by both Indian and
international exhibitors,
and is confident that
ELECRAMA 2018 will
be the grandest of all
ELECRAMA editions so
far. An interaction by
Venugopal Pillai.
We are extremely delighted with
the response to ELECRAMA 2018
— Vijay Karia, Chairman,
ELECRAMA 2018
interview

As we understand, ELECRAMA
2018 will be focusing on “Smart
Electricity”. Tell us more.
The focus is not just on Smart
Electricity but on various aspects of
electricity. The word energy is now
changing to electricity and is seeing
some exciting developments to look
forward to. Therefore ELECRAMA
2018 focuses on the new areas of
electricity. To understand and see
what kind of infrastructure is needed
and to support this commitment
Indian government has promised to
reduce carbon footprint, pollution
and not to increase costs per unit
to make consumption of electricity
cost efficient, we are trying our best
to bring everything possible on one
platform.
What inspired the change in venue
from Bengaluru where two editions
(2014 and 2016) were held?
We wanted this ELECRAMA to be
amongst the biggest exhibitions
ever. Noida has one of the country’s
largest grounds and we believe that
this edition will be much larger
than the previous traditionally-done
ELECRAMAs. One of the other
major reasons was we wanted to
explore new markets this time and
showcase the ideology and world
class technology to the national
capital. This ELECRAMA will have
lot of foreign visitors and delegates
and Delhi is more accessible in
terms of international air traffic.
People often speak of ELECRAMA
as a “recession-proof” event
where exhibitors are most keen to
participate even amidst economic
slowdowns. We could perceive this
especially in the 2010 edition. What
makes ELECRAMA so compelling?
Yes, Elecrama is a recession-proof
event because it is an exhibition
where lot of dedicated people,
buyers, utilities and companies
participate. The major reason of
their participation is that they
see an opportunity to experience
latest technology and products.
Not just Indian organizations
but international organizations
now recognize India’s potential
to provide quality, consistency
and advance technology. Even
those remotely associated with the
electrical industry cannot afford to
miss ELECRAMA.
Please discuss the active support
that the government—power
ministry and the ministry of heavy
industry in particular—has been
providing to ELECRAMA, over the
years.
ELECRAMA 2016 saw railways,
heavy industry and power from the
government side showing interest.
Utility heads from across the world
came to participate in ELECRAMA.
Government’s goal to electrify entire
India and its “Make in India” for the
world campaign is aligned with the
core ideology of ELECRAMA.
Our government is committed to
completelyremovepowerTDlosses
and they identify with this platform
and bring in active participation
through pavilions and concurrent
events throughout the five days of
the event.
Over the years, ELECRAMA has
been contributing to the growth
of the Indian electrical equipment
industry and even projecting India
on the world map. What is your
expectation from Elecrama 2018?
India is always on the world map as
far as investors are concerned. In the
infrastructure and electrical segment
there is going to be paradigm
shift, where we are moving from
fossil fuels to renewable energy,
from antiquated networks to smart
grids, from metropolitan cities with
creaking infrastructure to smart
cities. This trust of the government
has led to a lot of interest, especially
in the infrastructure sector, and we
anticipatethatELECRAMA2018will
further fuel this increased interest in
the electrical segment, apart from
the electronics and electric vehicle
sector. n

BHEL starts work on Yadadri supercritical power project
With the revised letter of intent now in hand, Bharat Heavy Elec-
tricals Ltd has commenced worked on building the 4,000-mw
Yadadri supercritical thermal power plant for state utility Telangana
State Power Generation Corporation Ltd (TSGENCO). The project is
coming up at Damaracherla in Nalgonda district of Telangana.
The EPC order, which includes five sets (boilers and turbine-
generators) of 800-mw power units, is valued at Rs.20,400 crore.
This is believed to be the single-largest order in the history of India’s
power sector.
The revised letter of intent, it is believed, was necessitated due to a
fresh clearance from the ministry of environment, forests and climate
change. The project will take shape on 2,800 acres of land out of
which nearly 2,100 acres is forest land falling under the Veerlapalem
forest block, it is learnt. BHEL had to seek fresh forest clearance
as the original environmental impact assessment (EIA) report had
inadequacies. BHEL subsequently appointed a new consultant and
had the EIA prepared afresh.
The Yadadri power plant will run on both domestic and imported
coal. While the domestic coal will be supplied by Singareni Coal
Collieries Ltd, the imports component will be contracted from
Indonesia, Australia and South Africa.
Performance in FY17
In FY17, BHEL commissioned 8,570 mw of power generation
equipment that included three supercritical sets of 660 mw and one
of 800 mw. In the XII Plan period (April 2012 to March 2017), BHEL
commissioned a total of 45,274 mw that surpassed the government-
set target by 9 per cent.
Supercritical orders
BHEL has so far received orders for 48 supercritical steam generators
(boilers) and 41 supercritical turbine-generators. Out of these, 15
supercritical boilers and 13 supercritical turbine-generators have
already been commissioned.

VIEW POINT
Time has come for anti-dumping duty
ANielsen study has found out that out of
the total LED bulbs available in the Indian
markets, almost 76 per cent are spurious. In
addition, the report also states that 48 per
cent of the LED bulb brands had no manu-
facturers’ addresses and 31 per cent had no
manufacturers’ names, both mandatory legal
requirements in the country.
The Indian lighting industry has been
consistently cautioning against low quality
imports into the country. Most of these are
Chinese imports which do not meet any ap-
plicable standards, cause a huge loss to the
exchequer and the organized industry.
The report also found that a majority of the
LED brands available in the market, do not
meet the norms of BIS and the Ministry of
Electronics and Information Technology.
Today, BIS focuses on safety standards,
but the compliance process is very weak.
There are no performance standards that
are mandatory and this could turn out to
be the Achilles heel of the most energy ef-
ficient lighting source. We firmly believe that
the time has come to strengthen the safety
and performance standards of BIS and make
them mandatory. In addition, the compliance
standards should call for punitive damages,
if not adhered to. The maturity of an industry
is also witnessed from the strong standards
that it adheres to and this is needed in our
case too.
The Government should take strict action
against low quality products that do not ad-
here to safety standards prescribed by BIS
and systems should be put in place so that
distributors and retailers are not allowed
to sell them. Any potential mishaps due to
these LED bulbs have the potential to derail
the Energy efficiency campaign run by the
Government and do massive damage to the
industry per se.
The staggering numbers are also a blot of
the PM’s Make in India campaign, since most
of these are low quality Chinese imports. In
order to ensure that only quality products
are available in the market, the Government
should immediately ensure that the procure-
ment for EESL and Government bodies is
from Indian manufacturing only.
We think that time has come, when some
sort of anti-dumping duty should also be
imposed on these imports so that the Indian
consumer does not suffer.

Siemens tests world’s first 1,100kV HVDC transformer
Achievement
he world’s first transformer,
which Siemens developed
and manufactured for high-
voltage direct-current (HVDC)
transmission systems with what is
currently the highest transmission
voltage of ±1,100kV, recently
passed its type test, Siemens said in
a release.
Siemens developed, manufactured
and tested the HVDC transformer
in its transformer factory in
Nuremberg. It is the first of a total
of seven ±1,100kV transformers that
Siemens and an unnamed partner
company are building for what is
currently the world’s largest HVDC
transmission system. This type
of transformer is among the most
powerful single-phase units in the
world, with a transmission capacity
of 587.1 MVA. Siemens is building
the transformers in its network of
factories led by its Nuremberg plant
in Germany, in cooperation with its
factory for HVDC transformers in
Guangzhou,China,aswellasanother
Chinese partner. These factories
are manufacturing the machines
according to the specifications and
documentation of the lead factory in
Nuremberg. Commissioning of the
world’s largest HVDC link– and thus
also the transformers–is scheduled
for 2018.
Siemens developed all key
componentsofthistypeoftransformer,
thus reaching a new transmission
level in HVDC technology. The
workflows for manufacturing
and testing this product were
challenging due to the transformer’s
extreme dimensions (LxWxH: 37.5m
x 12.0m x 14.5m). Nevertheless, the
±1,100kV prototype was able to pass
every test in terms of functionality,
emissions and load level. The type-
tested HVDC transformer is now
being prepared for its long journey
to China by road and sea.
“With successful testing of the
world’s first HVDC transformer for
a transmission voltage of ±1,100kV,
we have set a new benchmark
in direct-current transmission,”
states Dr Beatrix Natter, CEO of
Power Transformers at Siemens
Energy Management. “Experience
and ingenuity are what made this
development possible. It makes
direct-current transmission over
long distances more efficient for
our customers, because higher
transmission voltages mean lower
transmission losses,” she added.
Deployment:Thetransformerswill
be installed in the Guquan converter
station of the HVDC link between
the Chinese cities of Changji
(Xinjiang) and Guquan (Anhui).
This is the world’s most powerful
HVDC transmission system in terms
of transmission capacity, voltage
and length. It will transmit power
with a DC voltage of ±1,100kV
for the first time anywhere in the
world. The HVDC link is 3,284 km
long and will transmit electricity
from the northwestern Xinjiang
region to Anhui Province in eastern
China. With a transmission capacity
of 12 GW, it will replace what was
previously the most powerful system
with a capacity of 10 GW.
AC to DC: In such HVDC systems,
transformers are used to feed power
from conventional AC transmission
grids into what are known as
converter stations. These generate
the DC voltage on one side and
convert it back to AC voltage on
the receiving side. Due to the type
of connection to the converters, the
transformers will also be loaded with
the very high DC quantities of the
transmission voltage and current. n
T
The 1,100kV HVDC transformer’s has extreme
dimensions of 37.5m (L) x 12.0m (W) x 14.5m (H). Seven
such transformers will be supplied by Siemens for the
1,100kV Xinjiang-Anhui HVDC transmission link in China.

Renewables
ABB provides technology for pollution-free e-rickshaw
ABB India is providing critical technology through its solar invert-
ers for solar powered charging stations for e-rickshaws at four
locations in Jabalpur, a release from ABB said. As the sun hits the
solar panels at the charging station, generating the direct current (DC)
energy, the ABB inverters convert that power to the alternating current
(AC) used in charging the e-rickshaws. The solar powered charging
stations are part of a renewable energy project initiated by the Ja-
balpur Smart City Corporation. The solar panels are also connected
to the state grid to feed in additional power generated through net
metering. The ABB inverters come with Wifi connectivity for remote
monitoring and centralized billing provisions in the future.
Jabalpur currently has 400 licensed e-rickshaws plying in the city.
This pilot project is an endeavor to provide these e-rickshaws with
renewable-energy-powered charging stations. The ultimate aim is to
also convert the 5,000 diesel-run city rickshaws to a cleaner, greener
mode of propulsion, reducing carbon emissions in transportation and
bringing down pollution levels in the city. Currently, conventional rick-
shaws emit at least 46 tonnes of CO2
per day in the city. This project is
one of the first of its kind in the country, demonstrating green genera-
tion and green usage. The solar powered charging stations, capable
of generating 50 kilowatts of electricity, take between 7 to 8 hours for
a full recharge, enabling the vehicle to travel 100 to 150 km.

for safety of workers, stressing that
no productivity would be possible
without safety. She went to suggest
that safety should be part of the
exercise of skilling the labour
force. Sen also explained why the
involvement of a third party like
3M proves effective. “While one
can expect workers to learn from
their employers, what we have seen
is that when a third-party goes and
trains, they listen because we are
not their ‘normal supervisors’”.
Sen explained the purpose of the
collaboration with DGFASLI is to
create awareness so that workers can
understand products better and take
up self-protection more seriously
and consciously.
Meanwhile, 3M has pledged that
through such safety vans, it will
cover one million workers in three
years. “But we are sure that we can
cross it much sooner,” observed Sen.
Dr Avneesh Singh, Director
General, Factory Advice Service
Labour Institutes (DGFASLI) noted
that while several collaborative
ventures have been launched in the
past,allofthemwerewithgovernment
agencies. The collaboration with 3M
represents the first collaboration with
a private entity. Dr Singh explained
that DGFASLI would draw up the
logistics plan for the “Suraksha
Rath,” identifying the exact locations
(industrial clusters) where the safety
van would hold demonstrations and
training. DGFASLI would also be
responsible for collecting feedback
and sending the same to the Union
ministry of Labour Employment,
under which it falls.
When asked about whether this
was the first such safety awareness
venture for 3M, Debarati Sen
explained that such campaigns are
part of 3M’s activities worldwide and
have already been held in countries
like China, Mexico, US, among
several others.
In response to a question on
about whether the involvement of
foreign companies in India, either
as joint ventures or wholly-owned
subsidiaries, has influenced overall
safety standards in India, Dr Avneesh
Singh was positive. “Companies
from developed countries come with
much higher standards of safety and
protection. Laws are more stringent
there,” Dr Singh remarked. The high
standard of safety of companies from
developed nations was definitely
helping Indian companies, the
Director General felt.
Dr Singh cited the example of the
readymade garment industry that is
present in India in a big way. There
was a time when multinationals
took to Bangladesh to set up their
processing units, with a view to
save on labour and material costs.
While much demand started shifting
from India to Bangladesh, serious
concerns with regard to safety issues
starting cropping up, and several
factory accidents were reported. It
was then that the industry started
returning to India. n
