Abstract

Electrical energy is an essential part of modern life important to the economy of country. It is importance is very much for industrial as well as commercial purpose as for lighting, heating, cooling and for operating appliances as computers, electronic machinery and public transportation systems. Mostly the loads are inductive due to which electric current lags the voltage. As a result, larger current is needed to compensate the inductive load compare to resistive load which is not a good sight for power efficiency. To overcome this problem we have developed an Automatic power factor correction system that reads power factor from line voltage and line current. When power factor is not unity the system uses the capacitor bank to compensate excessive components and improve power factor nearly unity.
