Instructions for use

The high frequency current sensor is suitable for 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 sensor uses Rothschild coil operation mode, which surrounds multiple coils of conductive coil on a ring magnetic material. The high-frequency alternating electromagnetic field caused by high frequency current passing through the center of the magnetic core will generate induced voltage on the coil. There is no electrical connection between the measurement loop of the sensor and the measured current, which is a non-invasive detection method, and the equipment under test does not need to be shut down.
