Frequently Asked Questions 

1. What is the power transformer used for?

Power transformers are frequently used to step up and step down voltages at the electrical power generating station and distribution stations.

2. Why is the transformer used in kVA?

Transformers are used and rated in kVA, to account for power losses. The total heat losses in a transformer depends on volt-ampere (VA) only and not on the power factor of the load. That is why the transformer rating is given in kVA and not in kW. 

3. What is the difference between a power transformer and an instrument transformer?

A power transformer is primarily used in power transmission and distribution to either step up or step down a voltage level. While an instrument transformer is used in a circuit for the measurement of voltage or current.
