Description

Overview 

GAOTek DC system ground fault locator is to find the insulation fault of voltage level 48 V, 110 V, 220 V DC system such as indirect grounding, non-metal grounding, Loop grounding, positive and negative grounding, positive and negative balance grounding, AC into DC fault, multi-point grounding. Portable DC ground locator with High resolution sensor unit performs the acquisition of leakage current for grounding point of DC system. It can immediately measure and locate the grounding insulation impedance within 600 KΩ at 220 V voltage level to solve the insulation fault in DC system.
