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. 

Single Phase Transformer ď‚—

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. ď‚—

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.

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. ď‚— 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. ď‚— 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. ď‚—

Distribution Transformer ď‚—

The purpose of a distribution transformer is to reduce the primary voltage of the electric distribution system to the utilization voltage serving the customer.

ď‚—

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.

ď‚—

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.

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. ď‚— 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. ď‚— Generally the time interval, for which transformer designed to carry the maximum fault current through it safely, is taken as 9 second. ď‚—

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. ď‚— 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. ď‚—

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. 

Residual Voltage Transformer

ď‚—

RVTs are used for residual earth fault protection and for discharging capacitor banks.

ď‚—

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.

ď‚—

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.

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.
