JHZXPD-1 on-line monitoring system for partial discharge
The system is mainly composed of UHF sensors, signal transmission, data collection devices and background data processing
The UHF discharge signal generated inside the equipment is monitored by the UHF sensor, transmitted to the processor through the radio frequency cable for amplification processing, and then entered the main server for analysis, display and storage. When an abnormal discharge signal is detected, an alarm is issued, and the first time Notify the supervisor
