Answer / ashfaq

it will definitely improve power factor,but the problem is
if we installed more capacitor than required then receiving
voltage will be greater than sending voltage,farrantic
effect will happen

Answer / subhasish roy chowdhury

either way, if the angle fi of P.F cos fi is close to 90 degree (close to Y axis) or 270 degree (close to Y' axis) the effective/usable power is going to reduce because value of cos fi will reduce as fi moves from o degree to 90 degree or 0 degree to 270 degree. So when we are using capacitor bank it should be used only to nullify the lagging part and should not be used in excess.
