GIS partial discharge online monitoring system

This system can be used for real-time monitoring of the partial discharge status of GIS of 126kV and above. It can automatically convert partial discharge activity data into graphics and management report formats and upload them to the server, automatically send out alarms for the degree of danger of partial discharge activities, notify users by email or SMS, and provide auxiliary analysis and maintenance of GIS status Basis for decision-making.
