Product Description

ZXDW-5A large ground network grounding resistance tester

    

     

ZXDW-5A large-scale ground grid grounding resistance tester can measure substation ground grid (4Ω), thermal power plant, microwave station (10Ω), lightning rod (10Ω) multi-purpose model, the use of new frequency conversion AC power supply, and the use of microcomputer processing control and signal processing measures, a good solution to the anti-interference problem in the test process, simplify the test operation process. The precision and accuracy of test results are improved, and the labor intensity and test cost of test personnel are greatly reduced.

This instrument is suitable for testing power frequency characteristic parameters such as power frequency grounding impedance and soil resistivity of various grounding devices. The instrument adopts different frequency anti-jamming technology, which can accurately measure the data under power frequency 50Hz under strong interference environment. The test current is 5A, which will not cause the potential of the grounding device to be too high during the test, and it also has a great anti-interference ability, so it can be measured without power failure.

Features

1. Good power frequency equivalence of measurement. The test current waveform is sine wave, and the frequency is only 5Hz different from the power frequency, and two frequencies of 45Hz and 55Hz are used for measurement.

2. Strong anti-interference ability. The instrument adopts different frequency method and modern software and hardware filtering technology, which makes the instrument have high anti-interference performance, and the test data is stable and reliable.

3. High precision. The basic error is only 0.005Ω, which can be used to measure large ground grids with small ground impedance.

4. Powerful. Can measure the grounding resistance of current pile, voltage pile, grounding resistance of ground network, on-resistance, soil resistivity.

5. Easy to operate. Full Chinese menu operation, directly display the measurement results.
