Frequently Asked Questions

1. 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.

2. Can transformers be operated at voltages other than the prescribed voltages?

Transformers can sometimes be used at voltages that are lower than the rated voltage. However the voltage rating of a transformer should NEVER be exceeded unless taps are provided for this reason. Note, when operating below the rated voltage the KVA capacity is reduced correspondingly.

3. What is meant by impedance in transformers?

Impedance is the transformer's ability to restrict current and is expressed in percentage.
