Product Description

General Information

GD2136H 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-2132 Cable Fault Locator
3. GD-2133 Cable Fault Tester
4. 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.
