Abstract:
Power capacitor is basically an electrical device used for improving power factor of the electrical power system when the load is inductive. Most of the industries use induction motors, welding transformers and other machines with wire wound components which results Low power factor in the neighboring distribution line. This causes big KVAR loss and wastage of energy. Therefore Improvement of power factor is considered to be one of the important measures of energy conservation. Use of power capacitors improves the power factor of the line to which they are connected and thereby improving power factor for neighboring industry also. In certain applications, capacitors are used to store energy also, but with limited use.
