The procedure of the Earth Resistance Tester improves the measurement accuracy
Release Time : 2017-03-08 View Count : 次At present in the power system,Earth Resistance Tester the grounding resistance tester is the main instrument for resistance measurement. It can accurately measure the grounding resistance and effectively maintain the safety of the circuit operation. The measured power frequency has good equivalence. The test current waveform is a sine wave. Strong anti-interference ability. The use of different frequency method measurement,Earth Resistance Tester combined with modern hardware and software filtering technology,Earth Resistance Tester makes the instrument have high anti-jamming performance, and the test data is stable and reliable.
High precision. It can be used to measure large ground networks with very low ground impedance. Powerful. Various resistances can be measured. easy to use.Earth Resistance Tester All Chinese menu operation directly displays the measurement results.Earth Resistance Tester The wiring labor is small and no large current line is needed. In order to prevent the power frequency disturbance generated during the operation of the power grid and improve the accuracy of the measurement results,Earth Resistance Tester the ground resistance tester must comply with certain regulations during use. The experimental current of the power frequency high current method shall not be less than 30 amperes.
The multi-purpose models of measurable substation ground grids,Earth Resistance Tester hydropower plants, and lightning rods use a new type of variable frequency AC power supply,Earth Resistance Tester and use microcomputer processing control and signal processing methods to deal with the anti-jamming problem in the test process. It is suitable for testing the power frequency grounding impedance,Earth Resistance Tester power frequency characteristic parameters and soil resistivity of various grounding devices. The grounding resistance tester selects different frequency anti-jamming technology,Earth Resistance Tester which can accurately measure the data at a power frequency of 50 Hz in a strong disturbance environment. The test current of 5A will not cause the potential of the grounding device to be too high during the test,Earth Resistance Tester and also has a strong anti-jamming capability,Earth Resistance Tester so it can be measured without power outages. Simplify the experimental operation process, improve the accuracy and precision of the test results,Earth Resistance Tester and greatly reduce the labor intensity and experimental costs of the experimental personnel.
