Various inductive loads used in all industries deals with the problem of power factor improvement. Capacitor bank connected in shunt helps in maintaining the power factor closer to unity. They improve the electrical supply quality and increase the efficiency of the system. Also the line losses are also reduced. Shunt capacitor banks are less costly and can be installed anywhere. This paper deals with shunt capacitor bank designing for power factor improvement considering overvoltage for substation installation. The main reason of installing a capacitor bank is to reduce electricity costs. This inappropriate installation without enough study gives rise to a great variety of technical problems. Therefore, the fact that capacitor banks are designed for long-term use should be considered. A capacitor consists of two conducting plates separated by a layer of insulating material called the dielectric. A capacitor may be thought of as a battery that stores and releases current to improve the power factor.
