4. About 132/33 KV substation
A substation is a part of an
electrical transmission and
distribution system.
Substation transforms voltage
from high to low, or the reverse, or
performs any of several other
important functions.
To design a 132 KV / 33 KV EHV
sub a station where the incoming
power is received at 132 KV from
a generating station.
In this substation, the power is
coming from the 220 KV GSS
bagru (RICCO industrial area).

5. Introduction of Power Distribution plant
A power plant is an industrial facility that generates electricity from primary energy. Most power
plants use one or more generators that convert mechanical energy into electrical energy in order to
supply power to the electrical grid for society's electrical needs.

6. Single line diagram
Definition: Single line
diagram is the representation
of a power system using a
simple symbol for each
component. The single-line
diagram of a power system is
the network that shows the
main connections and
arrangement of the system
components along with their
data (such as output rating,
voltage, resistance,
reactance, etc.).

7. Power transformer
A transformer is a passive electrical
device that transfers electrical energy
from one electrical circuit to another, or
multiple circuits.
A transformer consist of two electrically
isolated coils and operates on Faraday’s
principal of “mutual induction”, in which
an EMF is induced in the transformers
secondary coil by the magnetic flux
generated by the voltages and current
flowing in the primary coil winding.

10. Measuring instrument
This transformer test instrument has a true three-phase reference standard.
Additionally, this PT/CT analyzer has optional three-phase current and voltage
sources for ANSI C12 phantom load meter testing. You also have the option to add
an MTA-15Z accessory to facilitate ANSI C12 meter testing on self-contained
meters at the customer’s site or in the lab.
Voltage testing device
Transformer test instrument
The tettex from HAEFELY is an instrument transformer test equipment that is a full
product line for high-accurate calculation of various kinds of present instrument
and voltage instrument transformers conforming to IEC and ANSI standards. This
device is allowed to use for type tests, production testing, maintenance testing,
and repair. It has a scale that covers measuring instruments, software, standard
current comparators, standard voltage dividers, burdens, and power supplies

11. Circuit breaker
VCB is used for medium-
voltage ratings (like
11KV and 33KV). It is
widely used for the
substation for overload
or high current
protection. And it is
used for transformer
switching, reactor
switching, capacitor
bank switching, etc

12. Isolator
An isolation transformer is a
transformer used to transfer
electrical power from a source of
alternating current (AC) power to
some equipment or device while
isolating the powered device
from the power source, usually
for safety reasons or to reduce
transients and harmonics.

13. Bus coupler
A bus coupler is a device that is
used to couple one bus to the
other without any interruption
in power supply and without
creating hazardous arcs. A bus
coupler is a breaker used to
couple two busbars to perform
maintenance on other circuit
breakers associated with that
busbar

14. Bus coupler
A relay is an electrically
operated switch. It consists of
a set of input terminals for
single or multiple control
signals, and a set of operating
contact terminals. The switch
may have any number of
contacts in multiple contact
forms, such as make contacts,
break contacts or
combinations thereof.

15. WAVE TRAP
A line trap, also known as
wave trap, or high-frequency
stopper, is a maintenance-
free parallel resonant circuit,
mounted inline on high-
voltage (HV) AC transmission
power lines to prevent the
transmission of high
frequency (40 kHz to 1000
kHz) carrier signals of power
line communication to
unwanted destinations.

16. BATTERY BANK ROOM
A battery room is a room that
houses batteries for backup
or uninterruptible power
systems. The rooms are found
in telecommunication central
offices and provide standby
power for computing
equipment in data centers.

18. CONCLUSION
Electricity plays an important role in our life. At the end of the training, I come to know about the various
parts of substations and how they are operated. Also, I learned about how transmission is done in various
parts of Jaipur ( Rajasthan ).
As evident from the ppt, a substation plays a very important role in the transmission system. That’s why
various protective measures are taken to protect the substations from various faults and their smooth
functioning. The power transmission corporation of Rajasthan limited takes such steps so that a uniform
and stable supply of electricity can reach every part of this state.
