description The utility model relates to a trouble surveying device of a low-voltage power cable, which is a device used for surveying the faults of an underground low-voltage power cable. At present, the faults of an underground low-voltage power cable can not be tested. The utility model is provided with an independent rough measurement high-voltage bridge circuit, an independent fixed-point capacitance energy storing circuit, and a high voltage power supply. The independent rough measurement high-voltage bridge circuit is provided with a high sensitivity galvanometer. The independent fixed-point capacitance energy storing circuit is provided with an energy storing device and an automatic discharge device. The utility model has the advantages of convenient test and high test precision.
