Shunt Compensation Technique for Improved Power Factor by Thyristor Switched Capacitor Inflexible AC Transmission System

Abstract

In an electric power system, a load with a low power factor draws more current than a load with a high power factor for the same amount of useful power transferred. The higher currents increase the energy lost in the distribution system, and require larger wires and othere quipment. Because of the costs of largere quipment and wasted energy, electrical utilities will usually charge a higher cost to industrial or commercial customers where there is a low power factor.
