DC Ground Fault Locators

GAOTek DC Grounding Underground Cable Fault Locator It is mainly used for underground power cable (especially the single core high voltage cable) metal sheath grounding fault accurately pinpointing, also can be used in the auxiliary pinpointing of core grounding fault (in the case of sheath have been destroyed).

GAOTek dc system ground fault tester present, the core problem of power system DC power supply grounding fault search is that the field interference is large, in different DC power supply and different working conditions measurement, most of the products will miss detect and misjudge, poor anti-interference.

This DC system power substation has a accuracy of 0.5%, grounding detection range of to 200 KΩ, and power supply of tested circuit.
