Description

GDXG Transmission overhead line open short circuit fault distance tester

General Information

The transmission line fault distance tester is used to measure the distance from the fault point to the measuring point (transformer) when the overhead transmission line is permanently grounded (short circuited) or open circuited (open circuit). The transmission line fault distance tester is used for overhead transmission lines of 10kV and above. When a fault occurs, as long as the faulty line is tested in the substation, the fault distance can be accurately measured, and the faulty tower can be determined, which is convenient for repair personnel. Quickly find faults and shorten repair time. This instrument must be used on the basis of a line outage. It has a small size, easy to carry, comes with a lithium battery, AC and DC, easy to operate.

The instrument can test short circuit, grounding fault of various types of power cables (voltage level 1kV ~ 35kV) , local telephone cables, FM communication cables, coaxial cables and metal overhead lines, ,It aslo can test cable breakage, poor contact, etc.; The length of the cable and the propagation speed of the electric wave on the cable can be tested.

Features

1. Fully functional
The test is safe, rapid and accurate; the instrument adopts the low-voltage pulse method, which can test various faults of the cable and accurately determine the distance from the fault point to the test point;
2. High test accuracy
The instrument adopts high-speed data sampling technology, and the A/D sampling speed is 100MHz, so that the instrument reading resolution is 1m, and the detection blind area is 1m;
3. High degree of intelligence
The test results are automatically displayed on the large-screen LCD screen with waveforms and data, and the fault diagnosis is intuitive; and it is equipped with a full Chinese menu display operation function, which does not require special training for operators;
4. Using non-volatile devices, the waveform and data will not be lost after shutdown, and it has the functions of waveform and parameter storage and recall;
5. With dual trace display function, the position of the dual cursors can be changed arbitrarily, and the direct distance or relative distance between the fault point and the test point can be directly displayed;
6. The test waveform of the faulty cable can be compared with the normal waveform, which is conducive to further judgment of the fault;
7. With the function of waveform expansion ratio, changing the waveform ratio, the waveform can be expanded for accurate testing;
8. It has the function of modifying the propagation speed at any time according to different cables under test;
9. Small size and portable shape, built-in rechargeable lithium battery for power supply, easy to carry and use.
10. With a USB interface, it can communicate with the computer through the host computer program.
