What is the thumb rule for calculating the P.F correction
Capacitor?? Say for 100 hp motor how much micro farad
Capacitor is needed .... Thumb rule so quick answer wanted

Answer Posted / himanshu

Motor is an inductive load so it is consuming
active power that depends on its load and
reactive power that is consumed by motor to set up its
magnetic field it is constant so we should connect a
capacitor which consumes the negative reactive power
according to p.f. correction requirement.
