An Electricity Inspection System of UHV Transmission Lines based on Beidou Satellite Communication

Abstract With the construction and development of UHV power transmission projects in China, safety are becoming increasingly important in the line operation and maintenance. The line operators must verify the electricity status of the transmission line before they carry out the work of maintenance. Due to the characteristics of UHV line, the electricity detection device on UHV line is different from the traditional ones. In this paper, an electricity inspection system based on Beidou satellite communication technology is established by means of non-contact Micro-Electro-Mechanism System (MEMS) electric field sensor. The system includes electricity detection device, handheld inquiry device and monitoring center. Experiments at actual transmission line verified the validation of the electricity inspection system.
