Portable Underground Power Cable Fault Locating System GD-4136L
General introduction
GD-4136L 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:
GD-2131L Impulse Generator
GD4132 Cable Fault Locator
GD-4133 Multi-pulse Cable Fault Tester
GD-4133S Multiple Pulse Coupler
GD-2131L Impulse Generatoris used to generate HV impulse when using impulse flashover method to detect high impedance fault.
GD4132 Cable Fault Locator main function is to locate poor insulation point, to detect circuit and depth of power cable.
GD-4133 Multi-pulse Cable Fault Testeris used to measure distance between cable faults. It is easy to operate and with friendly interface.
GD-4133S supplied pulse coupling signal for GD-4133 and isolate it from high voltage equipment.
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-4133 Cable Fault Tester, there are two locating ways: a. Low voltage pulse: If only using GD-4133, 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-4132 Cable Fault Locator, there are following functions: a. Audio frequency: locate high impedance, flash-over 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.
