At present, in the power system, the test of the grounding resistance of the large-scale grounding network is mainly measured by the power frequency and high current three-pole method. In order to prevent the power frequency interference generated during the operation of the power grid and improve the accuracy of the measurement results, the insulation preventive test regulations stipulate that the test current of the power frequency high current method shall not be less than 30 amperes. As a result, there are many problems such as bulky test equipment, complicated test process, high workload of test personnel, and long test time. KDWS-5A large-scale ground grid grounding resistance tester can measure substation ground grid (4Ω), hydrothermal power plant, microwave station (10Ω), lightning rod (10Ω) multi-purpose model, adopts a new type of variable frequency AC power supply, and adopts computer processing. Measures such as control and signal processing can solve the anti-interference problem in the test process, simplify the test operation process, improve the precision and accuracy of test results, and greatly reduce the labor intensity and test cost of test personnel. This instrument is suitable for testing the power frequency grounding impedance, touch voltage, step voltage, and other power frequency characteristic parameters and soil resistivity of various grounding devices. The instrument adopts different frequency anti-jamming technology, which can accurately measure the data under the power frequency of 50Hz in the strong interference environment. The maximum test current is 5A, which will not cause the potential of the grounding device to be too high during the test. At the same time, it also has a strong anti-interference ability, so it can be measured without power failure.
