In legging current reactive power is arise but in leading current which power will be arise ? and in this case, is active power more than rated ?
Answer Posted / raza
Reactive power is arise at both lagging and leading power
factors. But at lagging power factor, reactive power will be
positive and at leading power factor, reactive power will be
negative. At the same power power factors of lagging and
leading, no change in active power.
