Answer Posted / guest
normally the capacitors are switched on to bring the power factor nearer to unity i.e 1.
if load(kw)is almost equal to generator capacity (kva)or if power factor is between 0.9 to 1 we wont Switch on the capacitors.
capacitors are rated in kvar(kilo volt amp reactive )
apparent power=kvar=sqrt(3)*V*I*sin phi
