220V 110V 48V 24V Underground Cable Fault Distance Locator Live DC System

220V 110V 48V 24V Underground Cable Fault Distance Locator Live DC System

The PDF-3000A DC System Ground Fault Tester is used to find the exact location of the grounding point of the DC system of the power plant and substation under uninterrupted power conditions. The instrument introduces a new detection method---waveform analysis method in principle, its main features and advantages: high detection sensitivity, strong ability to check the distributed capacitance of the system, continuous power search, not affecting normal operation of the system, anti-interference ability Strong, safe and reliable. Waveform analysis method is to add a specific periodic voltage signal between the DC bus and the ground, detect the current of each branch through the caliper probe, analyze and calculate the phase and phase difference between the fundamental wave and the harmonic of the current signal, and then Determine if there is a ground fault and a ground fault point. The device is composed of a signal generator, a signal receiver and a caliper.

Features

1, Easy operation, just turn on the power switch can make the measurement.

2. Applying to 220V, 110V, 48V, 24V DC systems.

3. Wide application in power plant, substation, coal mine, chemical plant etc

4. Portable, easy carry, signal receiver comes with a battery, no external power supply

5. Search grounding points on line without affecting the normal operation of the system.

6. Strong anti-interference ability, which overcomes the influence of system distributed capacitance.

7. Intelligent charging management, reduce charging time and extend battery life.
