Development of line abnormal diagnosis system for overhead transmission lines

Overhead transmission line is the main way of power transmission, and its safe and stable operation is particularly important. Due to the complex network, transmission distance, large voltage grade serious problems such as frequent failure, this paper breaks through the transmission line fault location of traditional single, set induction electric wires, fault location, line insulation monitoring technology at an organic whole, developed of the transmission line abnormal diagnosis system, and realized the electrical characteristics of overhead transmission line multidimensional awareness. In this way, it can provide accurate information for maintenance personnel and ensure the safe and stable operation of the transmission network.
