Product Details

Functions
1. Complete functions
This transmission line fault distance tester tests faults safely, quickly, and accurately. It uses low-voltage pulse method and high-voltage flashover method to detect various cable faults, especially for cable flashover and high-resistance faults, it can be tested directly without burning through. If equipped with an acoustic positioning device, it can accurately determine the exact location of the fault.
2. High testing accuracy
This transmission line fault distance tester adopts high-speed data sampling technology with A/D sampling speed of 100MHz, making the tester read resolution 1m and detection blind zone 1m.
3. High intelligence
Test results are automatically displayed on a large-screen LCD in waveforms and data, making fault judgment intuitive. It also comes with a full Chinese menu display operation function, requiring no special training for operators.
4. Waveform and parameter storage and recall functions
This transmission line fault distance tester uses non-volatile devices, so waveforms and data are not lost after shutdown.
5. Dual-trace display function
It can compare the test waveform of the faulty cable with the normal waveform, which is helpful for further fault judgment.
6. Waveform expansion ratio function
This transmission line fault distance tester changes the waveform ratio to expand the waveform for precise testing.
7. Can arbitrarily change the position of dual cursors, directly displaying the direct or relative distance between the fault point and the test point.
8. Has the function to modify propagation speed according to different tested cables at any time.
9. Small size, portable shape, built-in rechargeable battery power supply, convenient to carry and use.

Product Introduction
The transmission line fault distance tester is suitable for overhead transmission lines of 35kV and above voltage levels. It is a special tester used to measure the fault point when a permanent grounding (short circuit) or open circuit (open circuit) occurs on overhead transmission lines. The line fault distance tester must be used on the basis of line outage. This transmission line fault distance tester is used to measure the distance from the fault point to the measurement point (transformer) when a permanent grounding (short circuit) or open circuit (open circuit) occurs on overhead transmission lines. This transmission line fault distance tester is suitable for overhead transmission lines of 35kV and above voltage levels. When a permanent single-phase grounding or disconnection fault occurs on the line, the fault distance can be accurately measured by testing the faulty line in the substation, determining the fault distance, which is convenient for repair personnel to quickly find the fault and shorten the repair time. The DFXL-S transmission line fault distance tester must be used on the basis of line outage. This transmission line fault distance tester has the characteristics of small size, easy portability, built-in battery for both AC and DC use, and has graphic and digital display functions, easy to operate.
