Capacitors are essential components in electrical distribution systems, primarily used to improve power factor. By offsetting the reactive power consumed by inductive loads like motors and transformers, capacitors enhance system efficiency, reduce losses and improve voltage. Alternating current (AC) is the dominant method for generating, transmitting and distributing electrical energy. This is achieved by having two oppositely charged electrical conductors separated by dielectric materials. ”. Should the voltage on a circuit fall below a specified level for some reason, a device called a capacitor can momentarily maintain the voltage at line value.
