Answer Posted / r.baskar

We all know that the factor "Power factor" comes only when
the voltage & current waves are travelling at a time
difference. This will happen due to the
inductive /capacitive nature of the load(Depends how the
load receives the power from the sourcei.e whether voltage
first (inductive)or current first(capacitive).

But at the time of producing the power, voltage and current
waveforms are starting from the source at the same time
only. Hence the question of power factor does not arise...

Hence DG is rated in kVA only...
