Frequently Asked Questions

1. 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.

2. What is meant by impedance in transformers?

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

3. What does a transformer rating mean?

The rating of a transformer is the maximum power which can be drawn from it without the temperature rise in the winding to go over what is considered safe for the specific kind of insulation used.
