Fault Analysis in Transmission Line and Time Inverse over Current Relay evaluation Using Matlab Simulink

Ankita Sharma, Pawan Nagar

Abstract


A power system is exposed to faults, because of natural disasters or by disoperation of the system due to operators' negligence. As a result, permanent damage to power system components leading to considerable costs for their replacement and in longer disconnections of power supply to customers, which is highly undesirable.
