Work flow of cable fault locator
I Cable fault testing system and cable fault tester
Introduction of cable fault locator
- Integrated trolley structure, suiatble for site work
- No need to connect the complex wires when site work, all testing modes and voltage classes could change by inside HV switch.
- Could locate fast for all 220V-220KV voltage classes cable faults
Main technical data of cable fault locator
- Test mode: Arc refection/multiple pulse, DC arc reflection, voltage sampling, current sampling, DC output.
- Sampling signal type: Arc refection/multiple pulse, DC arc reflection, voltage sampling, current sampling, low-voltage pulse
- DC high voltage output
0-32KV Negative polarity, maximum output current: 76mA
0-16KV Negative polarity, maximum output current: 152mA
0-8KV Negative polarity, maximum output current: 304mA
- Impact capacitance
0-32KV 4μF, maximum output energy: 2048J
0-16KV 16μF, maximum output energy: 2048J
0-8KV 64μF, maximum output energy: 2048J
- Ball gap impact discharge: weak control solenoid valve air gap, discharge cycle 3-12 seconds adjustable, and specially designed muffler device to meet the initial cable fault mute requirements.
- Protection
Zero voltage position protection, to protect operator and cable from wrong operation
