Abstract
A remote monitoring and fault diagnosis system based on passive wireless technology has been developed, which integrates with preventive test、live detection and online monitoring functions.The function unit has the advantage of IP-based、miniature and integrated. Online Monitoring of switchgear cabinet, transformer and electric cable’s partial discharge in the form of ultrasonic, Transient Earth Voltages(TEV) and High Frequency(HF) signals has been realized, and signals are transmissed to remote control center in configuration mode with wireless networking technology. Online monitoring, intelligent diagnosis and visual display of switchgear cabinet, transformer and electric cable’s three kind of PD signals have been successfully implemented. Field application proves that the system has effectively enhanced intelligent degree of distribution network equipment management, moreover, the goal of improving production efficiency and reducing mantanance cost has been achieved.Key words: smart distribution grid, passive wireless technology; remote monitoring, smart fault diagnosis
