Product Description Technical parameters of the analyzerProduct Name: Portable substation DC System Ground Fault LocatorModel No.: HBD-81Usage: 220V/110V/48V substation DC system earth fault detectProduct DescriptionHBD-81 DC Fault Tester 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 24V, 48V, 110V, 220V, 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.
