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. The audio method is used to complete the precise location of the general high-resistance and flashover fault points.
b. To pinpoint cable’s route, identify special cable.
c. For metallic breakdown(dead grounding), using magnetic-field measurement to locate accurately.
● It also can be used in DC HV withstand test.

GD-2132 Cable Fault Locator

Including transmitter, receiver, Inductive probe, potential type detection frame.It is suitable to test all kinds of power cable with metallic conductor.
Its main function is locating poor insulation point, detecting circuit and depth of power cable.

Features

● High sensitivity
● Low static drift
● High accuracy of locating
● Anti-interference
● LCD screen to show signal and status
● Built-in rechargeable Li-battery

Specifications

● Tracing and locating distance: local cable 3km, other cable up to 20km
● Locating impedance range: 0-5MΩ.
● Locating accuracy: ≤±10cm.
● Detection cable depth: <3m.

GD-2133 Cable Fault Detector

It can test faults of high-impedance flashover, high-low resistance grounding, short-circuit, cable disconnection, poor connection for all kinds of power cables (voltage degree 1kV-35kV) , local cable, communication cable, coaxial-cable and metal overhead line.
It also can measure cable’s length and propagation speed of electric wave speed on the cable.

Features

● Safe, prompt and accurate testing. It uses LV impulse method and HV flashover detection, which test all kinds of cable faults. Especially for the flashover and high impendance faults of cables, it can be directly tested without burning through; if equipped with a acoustic measurement locator, the precise position of the fault can be accurately determined.
● Using high speed data sampling technology. A/D sampling speed is 100Mhz, to make the reading resolution of the instrument is 1m and the detection blind area is 1m.
● Wave form and data automatically display on big LCD screen.
● Wave form and parameter storage, recall function.
● Function of comparing testing waveform of cable fault with normal waveform.
● Wave form extending function.
● Directly show fault point and testing point direct distance or relative distance.
● Modify speed of propagation any time according to different testing cables.
● Built-in rechargeable battery. Small size, portable to carry.
