HD3000 cable fault tester
Scope of application
It is suitable for measuring the high and low resistance, short circuit, open circuit, disconnection and high resistance leakage of various power cables, high frequency coaxial cables, local telephone cables and two or more evenly laid buried wires of various cross-sections and different media. And high resistance flashover fault.
Performance characteristics
(1) With its own DC power supply, it is convenient for on-site test, field test and mine cable test;
(2) The current sampler adopts a new sampling method, with simple wiring, intuitive waveform, and complete isolation from high voltage.
