Answer Posted / syed qamar abbas
Power factor is the cosine of angle between voltage and
current.If the voltage is leading and current is lagging
that means power is of lagging nature, if current is
leading voltage then its of leading nature and if both
voltage and current are in same pahse then its unity.By
injecting reactive power power can be corrected, if power
factor is lagging then it can be corrected by injecting
capacitive power (KVAR)by means of capacitor banks and if
its leading then by means of inductors.
