The aim of this work is to apply this technology in power system by designing a bidirectional system capable to transfer data over transmission lines from different sites to the control center in order to detect the faults and then correct them by sending control signals to trip the protective instruments when necessary via PLC.enPower systems, fault detectionPower Line Communication (PLC)Thesis
