Product descriptions from the supplier
At present, in the power system, the earth network grounding resistance test is mainly used in the industrial frequency high current three-pole method of measurement. In order to prevent the power grid operation frequency interference, improve the accuracy of the measurement results, insulation preventive test regulations: frequency current method of the test current shall not be less than 30 A. As a result, the test equipment is bulky, the test process is complex, the test personnel work intensity, test time is long and many other problems.
Large ground network grounding resistance tester adopts a new type of frequency conversion AC power supply, and the use of microcomputer processing control HZDW-III large ground network grounding resistance tester and signal processing and other measures, a good solution to the problem of anti-interference in the test process, simplify the test operation process, improve the accuracy and precision of the test results, and greatly reduce the labour intensity of the test personnel and test costs.
HZDW-III large ground network grounding resistance tester is a special instrument for measuring ground network grounding resistance and grounding conductivity between the grounding point. The instrument adopts frequency conversion anti-interference technology without high current measurement, can be measured in the substation under the strong interference environment of 50Hz accurate data, the measurement results by the large screen LCD display, comes with a micro-printer can be printed out. The instrument can measure the ground impedance and ground resistance at the same time, which can truly reflect the actual characteristics of the ground network.
