Product Description

Product Description

GD4136H Cable Fault system is important tool to maintain all kinds of cables. It uses various detection way to test cable faults, which is suitable for different levels voltage power cables and communication cables.
 
The system contains below units:
1.GD-2131H Impulse Generator
2.GD-4132 Cable Fault Locator
3.GD-4133 Multi-pulse Cable Fault Tester
4.GD-4133S Multi-pulse Coupler
5.Other accessories
GD-2131H Impulse Generator
It's used to generate HV impulse when using impulse flashover method to detect high impedance fault.
 
Features

Strong burning ability, max.burning power is 1000W, breakdown point can be burned in short time and the resistance of breakdown point is decreased.
If working together with GD-2133 Cable Fault Tester, there are two locating ways:
a. Low voltage pulse: If only using GD-2133, open circuit and low impedance grounding faults of cable can be located, and the length of cable can be measured or wave speed of cable can be detected.
b. High voltage flashover: The discharging pulse voltage waveform of fault point is sampled by discharging sphere gap, which can locate fault distance.
Generate impulse of fixed frequency. If working together with GD-2132 Cable Fault Locator, there are following functions:
a. Audio frequency: locate high impedance, flashover faults.
b. To pinpoint cable's route, identify special cable.
c. To metallic breakdown(dead grounding), using magnetic-field measurement to locate accurately.
It also can be used in DC HV withstand test.

GD-4133 Cable Fault Detector
GD-4133 Cable Fault Locator is used to measure distance between cable faults. It's easy to operate and with friendly interface.
It can be used alone under the low voltage pulse mode. Under the mode of pulse current, it needs to work with GD-2131 high voltage generator. Under the multiple pulse mode, GD-4133S coupler should be worked together. After distance locating, GD-4132 fault locator should be used for fault pinpointing. These products can be combined into a set of high performance and innovative cable fault testing system.
 
Features

7-inch LCD screen, friendly interface.
Multiple distance locating method:
Low voltage pulse method: it is suitable for the locating of the low resistance fault, short circuit fault, open circuit fault. It also can be used in the measurement of the cable length, the intermediate joints, T joints, and cable termination joint. This method also can be used to correct the wave velocity.
Pulse current method: It is suitable for distance measurement of the high resistance fault, breakdown fault. Using the current coupler to collect signals from the earth wire, it makes the user far away from the high voltage. This method is safe and reliable. 
Multiple pulse: the advanced way to measure distance. The waveform is easy to identify and the accuracy is high.
