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.

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 11.

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.

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.
