The large-scale grounding resistance tester is a multi-purpose model that can measure substation ground network (4Ω), hydrothermal power plant, microwave station (10Ω), and lightning rod (10Ω).Using a new type of variable frequency AC power supply, and adopting measures such as computer processing control and signal processing, it has solved the anti-interference problem during the test process.It simplifies the test operation process, improves the accuracy and accuracy of the test results, and greatly reduces the labor intensity and test cost of the test personnel.

  The instrument is suitable for testing the ground frequency impedance of various types of grounding devices, grounding resistance, auxiliary machine and other power frequency parameters and soil resistivity.The instrument adopts different frequency anti-interference technology, and can accurately measure the data under the power frequency 50Hz in a strong interference environment.The maximum test current is 5A, which will not cause the grounding device to have a high potential during the test. At the same time, it also has a strong anti-interference ability, so it can be measured without power failure.
