Wireless switchgear partial discharge sensor

The partial discharge signal can be continuously monitored online through the sensor installed in each switch cabinet

Monitor and detect the regular and continuous abnormal insulation status signal in the switch

Provide early warning of early failures, reduce unplanned downtime and reduce maintenance costs

Can provide alarms, trends and forecasts, data storage for at least 10 years

Computer operation without human influence
