In view of the status quot that partial discharge in high-voltage electrical equipment causes significant impacts on the safe operation of the power system, an ultraviolet endoscopic system of power equipment based on embedded system is presented. It consists of ultraviolet endoscopic probe, embedded computer system and Communication module. The system combines ultraviolet discharge detection and video endoscopic technology for special electrical equipment internal environment and can telemonitor ultraviolet discharge of power equipment. The system can run reliably and effectively to prevent the power accident caused by the discharge, which is proved by the simulation and high-voltage discharge test.
