The ground grid ground resistance tester is developed by the Ding Sheng Electric Power R&D Center according to the current national industry standard DL/T911-2004. The ground resistance test of this large ground grid adopts the mainstream power frequency high current three-pole method measurement technology to prevent power frequency interference during grid operation and improve the accuracy of test results. The ground grid ground resistance tester uses a new type of frequency conversion AC power supply, microprocessor control processing, and anti-interference signal processing measures to solve the anti-interference problem during the test, simplify the test operation process and the accuracy and precision of test results, and greatly reduce the labor intensity and test cost of test personnel.
The ground grid ground resistance tester is suitable for testing ground resistance in various voltage level substation ground grids (4Ω), power plants, microwave stations (10Ω), lightning rods (10Ω), and other places. The output of the large ground grid ground resistance tester uses dual frequency testing at 45Hz and 55Hz, with a maximum output current of 5A, which will not cause excessive potential of the grounding device during testing. This 5A large ground grid ground resistance tester also has strong anti-interference ability, allowing measurement to be carried out without power outage.

Functions of Ground Resistance Tester
1. Good power frequency equivalence. The test current waveform is a sine wave, with a frequency difference of only 5Hz from the power frequency, using 45Hz and 55Hz for measurement.
2. Strong anti-interference ability. This tester uses the frequency conversion method for measurement, combined with modern software and hardware filtering technology, giving the tester high anti-interference performance, and the test data is stable and reliable.
3. High accuracy of the 5A ground grid ground resistance tester. The basic error is only 0.005Ω, which can be used to measure large ground grids with very small ground impedance.
4. The 5A ground grid ground resistance tester has powerful functions. It can measure current stake, voltage stake, ground resistance, step voltage, and contact voltage.
5. Simple operation. Full Chinese menu operation, directly displaying measurement results.
6. The 5A ground grid ground resistance tester requires less wiring labor and does not require large current wires.
