ZIGBEE BASED-DIFFERENTIAL PILOT PROTECTION OF TRANSMISSION LINE

Jyoti Thakur, Hemant Pant

Abstract: This paper describes the limitations of the existing relays in the detection of fault. It also describes the benefits of using the differential pilot protection of the transmission line. Among other advantages one of its main advantages is its speed, which is required in a.c. systems to remain in synchronism (as angle d is to be kept small). In the end of this paper a model has been created in the laboratory by using two incandescent bulbs in parallel to create the difference in the two parts of the model, this difference is detected and appropriate action is finally taken to trip the circuit.
