Design, Manufacturing and Testing of Capacitor Bank for Power Factor Improvements

Abstract

Now days, increasing the need of electricity hence we required a different types of capacitors. In a power system along with constant power it is important to maintain the quality of power electronics devices for industrial, commercial and residential application with increasing non-linear load. Usually the electrical power supply companies impose a penalty, if the average power factor over a stipulated period falls below a certain value. A large part of load of bulk consumers are inductive in nature because of use of induction motors. This causes low power factor (lagging because of predominately inductive loads). Capacitors, on the other hand, constitute leading power factor load; thus compensating a major part of the inductive loads and result in power factor close to unity but still lagging in nature. This improvement of power factor fulfills the requirements of the utility. The main purpose of providing capacitor bank in case of power system is to supply reactive power to the system and they are installed at the receiver end, this is also called as VAR Compensation. The capacitor banks are called Static VAR Compensator.
