Answer / pillay

yes I agree with S. DALVI capacitors are theoretically
loss free equipments but due to manufacturing material
impurities and also externally fitted discharging
resistors there is some power loss/ consumption.The
manufacturers can give a more reliable figure
because it differs from make to make even though
not much.

Answer / s dalvi

100 KVAr Capacitor is normally used for power factor
correction. These capacitors offer reactive load (leading)
and theoretically the unit consumption will be zero.
