Overview

The partial discharge online monitoring system is a GIS based real-time monitoring device for partial discharge in substations. It is mainly suitable for online monitoring and analysis of partial discharge in digital substations with voltage levels of 110kV and above, achieving digitalization of substation maintenance.

Product Details

System Features

1. The UHF sensor designed based on the voltage of the production unit and various GIS structures has high sensitivity, up to 5PC.

2. The partial discharge online monitoring system adopts wireless signal technology to design filtering function, and the product has good stability.

3. The data analysis function of * determines the occurrence and development patterns of partial discharge phenomena during GIS operation, and provides corresponding basis for maintenance.

4. Software process monitoring, constantly upgrading and updating.

5. The system is equipped with overvoltage protection technology to prevent damage to the equipment.

6. Communication adopts RS485 or Ethernet port, which ensures stable and reliable communication.
