Description
Overview
GAOTek portable grounding fault locator is a high-precision DC fault tester. The device is based on the principle of DC current difference detection and introduces fast FFT transformation technology. Through detailed analysis of the amplitude frequency characteristics of the detection quantity, the contradiction between the safety and sensitivity of DC grounding fault detection is balanced. The equipment can detect various insulation faults, DC mutual leakage faults, and AC leakage faults in DC systems of various voltage levels such as 24 V, 48 V, 110 V, 220 V, etc. The equipment consists of an analysis host, a detector, and a current clamp. For different phenomena, DC square wave current clamp and square wave current clamp can be selected.
