Cable Fault Tester | TDR Cable Fault Pre-Locator | XHGG501B
Product Description
The cable fault tester is a special instrument for measuring and analyzing the fault status and fault distance of power cables. It adopts modern electronic technology to realize signal filtering, acquisition, data processing, graphic display and graphic analysis, and completes cable speed measurement, cable length test, cable fault distance test and resistance test.
This cable fault tester is suitable for low-resistance, short-circuit, open-circuit and disconnection faults of power cables, coaxial cables, street light cables, buried wires, etc. of various materials with different cross-sections and different media, as well as high leakage resistance and flashover high resistance faults. The technical parameters meet the standard requirements of DL/T 849.1 (General Technical Conditions for Special Tester for Power Equipment Part 1: Cable Fault Flash Tester) and JJF1042 (Calibration Specification for Cable Fault Tester).
Applications & Target Audience: Engineered for shipyard and marine engineering electrical teams, hospital and medical campus facility management units, defense installation maintenance teams, and oil and gas field electrical maintenance departments that pre-locate low-resistance, open-circuit, disconnection, high-resistance leakage and flashover faults in power cables up to 32km.
