Product overview

When partial discharge occurs inside the cable, the high-frequency current will propagate to the ground along the ground wire. A sensor is installed on the ground cable to detect high-frequency current signals for local discharge detection.
The circulation sensor uses the Roche coil working mode, and there is no electrical connection between the measurement loop of the sensor and the measured current, which belongs to the non-invasive detection method, and the equipment under test does not need to be shut down.
