3. HIGH TENSION CURRENT TRANSFORMER
• High Tension Current Transformer is used
to measure the current for HT consumer.
• Starlit Electricals is counted among the
leading manufacturers of Current
Transformers that are broadly used to
produce electric current.
• We manufacture a comprehensive range
of standard C.Trs.

4. THREE PHASE TRANSFORMER
• Three phase transformers are
designed to supply electric power to
three-phase systems. These electrical
devices have three circuit conductors
and may or may not have a neutral
wire.
• Three phase power is used by electric
power distribution grids and to power
large motors and other large loads.
• Three phase transformers carry many
product specifications, including
transformer type, winding turns,
cooling method, core type, and
mounting style. Performance
specifications, regulatory approvals,
and special features are also
important parameters to consider.

5. SINGLE PHASE TRANSFORMER
• Single phase transformers may be used to
increase or decrease the voltage from one
side of the transformer to the other. The turn
ratio or number of windings on the primary
and secondary sides of the device determines
the change in voltage.
• Step-up transformers produce a secondary
voltage that is larger than the primary
voltage. Step-down transformers have a
secondary voltage that is smaller than the
primary voltage. One-to-one transformers
well known as Isolation Transformer are single
phase transformers with a turn ratio of 1:1.

6. LIGHTING TRANSFORMERS
• Lighting Transformers are designed to
supply power to lighting equipment in a
commercial / industrial / domestic unit.
Its primary supply connected to higher
voltage 3Ph source and secondary is to
be connected to load.
• Lighting transformers serves as isolation
between primary and secondary, it also
restricts any high voltage spikes and
EMF coming with the raw mains
incoming power.
• Lighting Transformers are very useful
when system neutral is not available or
faulty i.e. where incoming supply is 3
phase 3 wire and lighting load is 220
Volt single phase. It also restricts short
circuit current in the load and saves
major accidents.

7. DISTRIBUTION TRANSFORMER
• The purpose of a distribution transformer is
to reduce the primary voltage of the
electric distribution system to the
utilization voltage serving the customer.
• A distribution transformer is a static device
constructed with two or more windings
used to transfer alternating current electric
power by electromagnetic induction from
one circuit to another at the same
frequency but with different values of
voltage and current.
• The standard Transformation Ratio of
Distribution Transformers is from 11000/433
V or 22000/433 V or 33000 / 433 V.
Sometimes an offload tap changer with
tapings of +/- 2.5% or +/-5% is also provided
to adjust to the local site conditions.
Depending upon the requirement, an on
load tap changer can also be provided.

8. EARTHING TRANSFORMER
• The rated voltage of an Earthing
or grounding transformer is the
line to line voltage on which it is
intended to be used.
• Current rating of this
transformer is the maximum
neutral current in Amperes that
the transformer is designed to
carry in fault condition for a
specific time.
• Generally the time interval, for
which transformer designed to
carry the maximum fault current
through it safely, is taken as 9
second.

9. HIGH VOLTAGE TESTER
• High voltage tester of breakdown
voltage testers( B D V testers) are
useful for measurement of
breakdown (flashover) voltage of
electrical components, insulation
materials instruments, transformers,
etc. to ascertain quality of
insulation material before planning
their usage in electrical
applications.
• For H.V Tester upto 5-10 KV the
front panel incorporates all controls
for operation of the unit. Easy to
use test probes connected to H.T
cables can be connected directly
voltage to the device under test.

10. AUTO TRANSFORMER FOR STARTING
INDUCTION MOTOR
• A 3 Ph Star connected Auto
transformer with a changeover
switch forms an Auto Transformer
starter. Initially the stator of the
induction motor is supplied with
reduced voltage through the Auto
Transformer using a suitable tap.
• This limits the starting current to a
safe value. The loading the system
and power loss involved are less in
this type and it can be used in delta
as well as star connected motors.
• The provisions of several tapping's
make the adjustments possible to
suit local conditions.

11. RESIDUAL VOLTAGE TRANSFORMER
• RVTs are used for residual earth fault
protection and for discharging
capacitor banks.
• The secondary residual voltage winding
is connected in open delta. Under
normal conditions of operation, there
is no voltage output across the residual
voltage winding.
• When there is an earth fault, a voltage
is developed across the open delta
winding which activates the relay. 3
phase RVTs typically have 5 limb
constructions.

12. VOLTAGE TRANSFORMER
• Starlit Electricals is leading
manufacturer and supplier of Voltage
Transformer in Pune.
• The Voltage Transformer isolates the
devices connected to their secondary
circuit from the network system. The
main function of the Voltage Transformer
is to reproduce the Primary Voltage on
its secondary side.
• The Voltage Transformer isolates the
devices connected to their secondary
circuit from the network system. Voltage
Transformers are specially designed for
measuring and protection applications.
