13.Why generators rated in kva

September 26, 2018 Posted by AK No comments

There are two answers to that question.

Answer no. 1:
There are two types of losses in the transformer/generator i.e core losses and copper losses (I^2R losses). Core losses are due to voltages and copper losses are due to current. Therefore if we rate the transformer in KW etc. We would not be able to accommodate the losses.

Answer no. 2:
The Power factor and current drawn from the load is un predictive. Whenever you design a transformer or generator you Simply cannot design that in Watts because the rating would continuously change due to varying power factors of the loads attached; and drawn currents.
