JC-OM400K switchgear local on-line monitoring system
The JC-OM400K switchgear local on-line monitoring system detects the electromagnetic wave radiation accompanying the partial discharge. The system scans the electromagnetic wave radiation in the frequency range of 10~100MHz and automatically determines the actual detection frequency of the partial discharge on site, and then the detection data is based on the partial discharge Pulse cluster counting mode display.
This system is an online monitoring device for detecting, analyzing and continuously monitoring the partial discharge signal in the high-voltage switchgear. As shown in the figure below, the JC-OM400K host in the system is used to process and digitize the signal obtained from the UHF sensor, and the upper computer is used to screen and analyze the partial discharge signal, complete the partial discharge pulse numerical record, and monitor the development status of the partial discharge volume. And other functions.
