Question 1 Why the rating of alternator in KVA. Answare losses of an alternator are iron losses which are voltage depend and copper losses are current dependend.

Question

Accepted Answer

The rating of an alternator is in KVA because the losses of an alternator are voltage dependent (iron losses) and current dependent (copper losses).

The rating of an alternator is determined by its ability to handle both voltage and current losses.
Iron losses in an alternator, which are voltage dependent, include hysteresis and eddy current losses.
Copper losses in an alternator, which are current dependent, include resistance losses in the windings.
The KVA rating takes into account both the voltage and current capabilities of the alternator.
For example, a 100 KVA alternator can handle both the voltage and current losses up to 100 KVA.
