JC-OM400D High Voltage Cable Partial Discharge Online Monitoring System

The JC-OM400D high-voltage cable partial discharge online monitoring system adopts a modular design scheme. The partial discharge pulse current signal at the cable body and the joint is coupled through the high-frequency current sensor installed on the ground wire of the cable joint; the coupled pulse current signal It is transmitted to the front-end monitoring collector through a coaxial cable, and the analog signal is amplified, filtered, and converted into a digital signal, and then transmitted to the test host through an optical fiber. The test host performs classification, identification, analysis and calculation on the signals of all sensors, and writes the discharge information data obtained through calculation into the database, and displays the monitoring results on the software panel of the monitoring system.
