A system for monitoring partial discharge of power distribution facilities comprises a monitoring computer and monitoring terminals mounted near the power distribution facilities, wherein each monitoring terminal comprises a partial discharge sensor, an RFID (radio frequency identification) reader, a single-chip microcomputer and a wireless communication module, each partial discharge sensor is mounted near each monitored power distribution facility, a signal output end of each partial discharge sensor is connected with an input port of each single-chip microcomputer, each RFID reader corresponds to an RFID tag on each power distribution facility, an output end of each RFID reader is connected with the input port of each single-chip microcomputer, and each single-chip microcomputer sends monitoring information to the monitoring computer through each wireless communication module. With the adoption of the system, when a partial discharge signal is detected by the aid of a detection coil, failure information and identity information of the power distribution facilities are sent to the monitoring computer together, so that the partial discharge is monitored in real time; the labor intensity of workers can be reduced, the system can assist the workers in finding out and eliminating potential failures timely, and safe and stable operation of an electric power system is guaranteed.
