Abstract
Overvoltage causes hazardous effect in the power system. There are two main sources of transient overvoltages on utility side one is capacitor switching and another one is lightning. These are the sources of transient overvoltages as well as a countless of other switching phenomena in the distribution system .The overvoltage occur in power system due to lightning is very high when compared with transient due to power electronic devices under switching phenomenon. Over voltage protection should be provided to the power system, to avoid damages and uninterrupted power. This paper presents various causes and its prevention methods of transient overvoltages
