Our Voltimum Experts answer your questions on a daily basis in our Technical Expertise area. This Question of the Day, concerning generators and transformers and their specified ratings, is answered by the ECA:
Question: Why does a transformer have its rating specified in kVA, while a generator is specified in kW?
Answer: In fact, both transformers and generators should have both kVA and kW ratings available. The kW rating is the unit of the power output, and kVA is normally the maximum demand, taking into account power factor and inductance.
