POWER CABLE FAULT LOCATOR-FOR LOW AND HIGH IMPEDACE FAULTS

Description

POWER CABLE FAULT LOCATOR-FOR LOW AND HIGH IMPEDACE FAULTS. Condition is "Used".
Description
Most power cables were buried underground, invisible, and out of reach. It is very difficult to find faults and often have to take long time to search them, not only a waste of manpower, material, but will also cause incalculable power failure loss. With modern new power cable fault testing equipment, it can find the fault point quickly, solve problems immediately and restore power supply.
Features
1. Combines low-voltage pulse reflection and pulse current testing methods, is suitable for the precise range finding of power cable high resistance, flashover, disconnection, and low resistance.
2. With high degree of intelligence, it can automatically determine whether the failure point discharge or not and automatically calculate the fault distance.
3. Compare with the traditional flash measurement instrument, which use resistance and capacitance divider measuring pulse voltage signals, the current sensor tests the pulse current signals in the grounding line with simple and convenient wiring, and good security with isolation of high-voltage equipment and the electrical circuit.
4. High testing accuracy:
When the distance < 1km, the test error <=1m
When the distance > 1km, the test error ≤0.5%.
5. English menu, easy to master and use.
6. It can preserve 20 testing waveforms permanently, no loss after the shutdown, is a replacement of printer. With a clock logo, you can read waveform file easily.
7. Using a large LCD screen with backlight. Adjust LCD display brightness through pressing keys.
8. Rechargeable nickel-metal hydride batteries, automatic charger management.
9. Small size, light weight, and portable design.
