Fault Detection in Transmission Line Using GPS and GSM

Abstract

A fault is an unexpected change of the system functionality ,which causes deviation of a plant behavior from that which is specified it . The problem of detect the location of fault in transmission line has become complex and expensive which depended on The current mechanism used to detect the fault in power transmission lines approximated by the calculation of the impedance obtained from voltage and current data. The works of this thesis is to find solution of how detected and located of fault in the transmission line by making use of GPS , GSM , microcontroller and power sensor the proposed system determine the location of fault accurately and quickly as possible. This process is done when the power sensor sensed the transmission line and found a fault in it ,then send signal to microcontroller (processing units) Alert occurrence of fault in the transmission line , after that The global positioning system detected the location of interruption and global system for mobile communication send message to supervisor this message include the details of location and number of line. At the end of research we have acquired results that it can be determined where thepower sensor the proposed system determine the location of fault accurately and quickly as possible.
