Over and under voltage protection for three phase system using GSM module

Abstract

For upgrading system efficiency automation is needed .besides for reliability and quality of electric service depends on automation nowadays .Automation is not only for upgrading the quality of a system it also reduces human effort as well as minimize time of production. We know that for over and under voltage problem many trouble happens in home and outdoor power system. For example insulation and appliance damage. In my report I will describe how over and under voltage problem creates problems to our system and also try to give a solution how to minimize this problem for three phase system by using automation which will be prepared by GSM module which will send sms alert for if fault occurs in system.
