What will hapen if we connect more capacitors than required
for powerfactor control? Exactly what will be the effect on
power system?
Answer Posted / 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.
