Product Description

XHHV535-4TS+XHGG502+XHLJ504  Underground Cable Fault Location system
Accurately and quickly detect the main insulation failure of power cables with voltage levels of 35KV and below; calibrate the cable length; accurately detect the direction and depth of the cable buried.

 The portable cable fault location system is a 1-phase mobile cable test and fault location system made in a form trolley. It is designed for

• Testing medium-voltage cables with direct current voltage Up to 32kV

 

• Pre-locating cable faults with the reflectometer XHGG502 based on the

low-voltage pulse reflection method (TDR),
high voltage flashover method (i e .DECAY, ICE),
arc reflection pulse reflection method (ARC single shot and ARC multi-shot) 

• Pinpointing cable faults with the acoustic method with 2000 j surge generator and suitable signal receiver.

Product Parameters

Cable fault pre-location: with the reflectometer XHGG502 based on the low-voltage impulse reflection method(TDR), and high-voltage decay(flashover) method (DECAY), multiple impulse(ARC/Multi-shot)arc reflection method.
XHGG502  cable fault pre-locator










There are three test mode of XHGG502, low voltage pulse, high voltage flashover, ARC multi-shot.

The below picture shows cable fault distance measured by using high voltage flashover test mode of XHGG502



--------------------------------------------------------------------------------------------------------------------------------------------------------
The below picture shows cable length or cable open circuit fault distance measured by using low voltage pulse test mode of XHGG502. When using the low voltage pulse method, it is not necessary to connect the high voltage pulse generator. Other test methods must be used in conjunction with a high-voltage pulse generator.

XHLJ504

 

The XHLJ504 cable pipe locator is composed of a high-power path signal generator(transmitter) and receiver

required for detecting buried cable paths.

The basic principle of the cable path meter is to use a path signal generator (ie, the path meter signal transmitting

host) to input a path pulse signal into the cable under test, thereby generating electromagnetic waves, and then

receiving them with a probe, and the receiver amplifies the received signal. After processing, the output is sent to

the earphone and the pointer meter.
 

This cable route tracer judges the buried path and depth of the cable according to the sound peaks, sound valleys

and the deflection degree of the pointer meter in the earphone.

 

Product Features

1. Using the traditional electromagnetic induction principle, strong anti-interference ability.

2. With over-current and short-circuit protection functions, it is safe and reliable.

3. High power output, not limited by cable length, open circuit can also find a path.

4. The output is steplessly adjustable, suitable for various test sites, with strong adaptability.

5. Super strong magnification, the detection depth is greater than 10 meters.

6. Ultra-low power consumption design, the quiescent current is less than 10mA.

7. The design of the analog meter, the signal strength and trend are clear at a glance.

8. The zero level can be adjusted arbitrarily, which is suitable for all kinds of strong and weak scenes.

The XHHV535-4TS high voltage pulse generator can be used impulse discharge and withstand voltage test in low and high voltage cable fault test. High-precision test cable fault sampling waveform module and small transformer are installed inside, which can truly achieve the effect of not being damaged by impact, and it also has the functions of automatic timing impact, manual impact and withstand voltage test.

This device integrates a high-voltage DC source, an energy storage capacitor, a discharge ball device, an automatic discharge device, and a voltage level switching device into a cart-type high-end experimental instrument. It is a trolley-type high-end experimental instrument. The equipment completely solves the problems of ease of use, portability, safety and reliability of traditional experimental devices.

When the XHHV535-4TS trolley-type high-voltage pulse generator is in use, after selecting the function switch, press the start button to perform high-voltage boosting work. After use, press the stop button, and the internal system will automatically release the remaining high voltage on the accumulator.
