IV. GD-2131H Integrated DC High Voltage Power Supply

GD-2131H integrated DC high voltage power supply unit is an integral part of the cable fault detection system and is used to detect the auxiliary high voltage power supply when using the impact flashover method to detect high resistance faults.

Features

1. Strong burning ability, the maximum burning power of 1000W, can burn through the breakdown point in a short time, reducing the breakdown point resistance.

2. In conjunction with the GD-4133 Cable Fault Tester, it has the following two positioning methods:

a. Low-voltage pulse method: GD-4133 can be used alone to locate the open circuit and low-resistance ground fault of the cable, and measure the cable length or verify the cable wave speed.

b. High-voltage flashover method: The pulse current waveform discharged by the fault point is sampled by the discharge ball gap, and the distance of the fault point can be located.

3. Generates a fixed frequency pulse that, in conjunction with the GD-4132 Cable Fault Locator, has the following features:

a. Use the audio method to complete the precise determination of the general high-resistance and flashover fault points.

b. Find the location (path) of the cable and identify the specific cable.

c. For metallic breakdown (dead ground), use magnetic field measurement to determine the point.

4. DC withstand voltage test is available.

5. Optional 30m or 50m cable reel for user convenience.
