TKHD-2000 Partial Discharge On-line Monitor System

Based on the UHF detecting GIS partial discharge principle, the system is applied for real-time on-line intelligent monitor on GIS of each voltage class. Advanced detection principle and hardware and software optimization design, makes the system can effectively filter various interferences, reliable found inside the equipment hidden trouble. The system USES the intelligence software distinguish system, realize the all-weather real-time on-line inspection, system operation friendly interface, can automatic analysis and damage degree of partial discharge type, make according to the operation state of GIS made correctly implement maintenance, avoid insulation accidents. System along with the function of data sent to the Internet, thus to realize the remote monitoring. Application of the system, will greatly improve the reliability of GIS, greatly reducing maintenance workload.
