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.
