Frequently Asked Questions

 1. 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. 

 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. How much would a new transformer save?

Since transformer technology has advanced dramatically over time, there are more benefits to upgrading an outdated transformer. An old transformer may have an average energy efficiency rating of 85%, which means 15% of the energy is wasted. The energy efficiency of a contemporary low loss transformer can reach 99.75%.
