Cable ground fault locator
It is suitable for fast and accurate location of ground point after power failure of 6-35KV fault line, small current grounding system of cable distribution network, detection of overhead line gold grounding, arc grounding, transition resistance grounding and other fault location.
After the fault line is shut down, the transmitter applies low frequency and high voltage to the line to make the fault repeat. The sensor is hung on the line with an insulated rod along the line to detect the applied current signal, and the data is transmitted wirelessly to the handheld receiver to display the measurement results. Before the fault point, the current signal continues to exist, and after the fault point, the current signal disappears. The fault location can be quickly determined by rough segmentation followed by precise fixing.
Cable ground fault locator
