Hardware Modeling of Fault Detection System for Three Phase Transmission Line

In electricity journey the generation of transmission, distribution, utilization of electrical power is called electrical technology. In power generation transmission and distribution many components are involved. So there are many types of electrical faults or faults like in transmission lines occurs in transmission system like line to line faults and line to ground fault in power system etc. In this paper, a prototype is presented for fault detection in three phase system. Mainly occurred in high voltage transmission lines, the present work accurately detects the distance of three phase fault from source system and displays it on control panel by using Arduino mega. In this work sensing device is used which is installed on the line even though L-L, L-G and any unsymmetrical fault occurs it will be shown on the display. Arduino is a heart of the present work. It detects the fault, analyses and classifies these faults and then, determines the fault distance.
