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

This thesis report is submitted in partial fulfilment of the requirements for the degree of Bachelor of Science in Electrical and Electronic Engineering, 2017.Cataloged from PDF version of thesis.Includes bibliographical references (page 43-45).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.Nasif AhmedB.
