Understanding Power Factor Correction in Generators
Capacitive power factor correction is a common method used in generators to improve the power factor. Capacitors are connected in parallel to the generator''s electrical system, creating a capacitive load. This capacitive load generates reactive power that counteracts the reactive power consumed by the inductive elements in the circuit.
