Product Description

XHHV515-8L+XHGG501D+XHDD503+XHGX507  Low voltage Cable Fault Location system
Accurately and quickly detect the main insulation failure of power cables with voltage levels of 15KV 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 15kV

 

• Pre-locating cable faults with the reflectometer XHGG501D based on the

low-voltage pulse reflection method (TDR), high voltage decay
method (DECAY), arc reflection pulse reflection method (ARC
single shot) and current pulse method (ICE)

• Pinpointing cable faults with the AMS method with 900 J surge generator and suitable signal receiver.

 

Cable fault pre-locator	XHGG501D: for cable fault distance test
Cable fault pinpoint locator	XHHD503:  cable fault pinpointing
High voltage surge generator	XHHV515-8L: To impact faulty cable to make it discharge
Cable fault comprehensive tester	XHGX507: for cable route tracing, for locating cable to ground fault.

XHDD503 is a classic portable power cable fault pinpointer independently developed and produced by our

company. After more than 50 years of precipitation, the acoustic-magnetic synchronization detection technology it

adopts has become very mature and widely accepted and recognized by users in the industry.

The XHDD503 cable fault locator is very small and light, it is packed in a protective PVC case, easy to carry after

the user finished detection.

The XHHV515-8L 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 XHHV5315-8Ltrolley-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.

Description

XHGX507 underground cable pipe locator is mainly used for cable fault location, cable identification,

cable path and depth measurement. It can complete tasks that could only be accomplished by a few sets of

instruments in the past.
 

Working principle

The underground cable pipe locator is designed based on the electromagnetic induction method and the

application of the communication principle.

1.The electromagnetic signal is generated by the transmitter, and the signal is transmitted to the underground

cable under test through different transmission connection methods.

2.After the underground cable induces the electromagnetic signal, an induced current is generated on the cable,

and the induced current propagates along the cable to the distance.

3.In the process of current propagation, electromagnetic waves are radiated to the ground through the underground

cable. When the receiver detects on the ground, the electromagnetic wave signal will be received on the ground

above the cable.

4.The position, direction and fault of the underground cable can be judged by the change of the received signal

strength.
