cable grounding fault locator

KDJK-10 distribution network overhead line single-phase grounding fault locator is suitable for 6-35kV overhead line single-phase grounding fault line, when the line is shut down due to single-phase grounding fault, the equipment can be accurately located at the docking point.

KDJK-10 single-phase ground fault locator for overhead lines in distribution network is a set of portable equipment, which can locate faults of multiple lines. The whole equipment consists of KDJK-10 transmitter, KDJK-A sensor, KDJK-B receiver and accessories. After the fault line is shut down, the transmitter applies ultra-low frequency high voltage signal to the line to make the fault repeat, and the sensor is hung on the line with an insulated rod along the line to detect the signal, and the data is transmitted wirelessly to the receiver on the ground, and the receiver displays the measurement result. Before the fault point, the current continues to exist, after the fault point, the current disappears. The fault location can be quickly determined by rough segmentation followed by precise fixing.
