Large ground substation ground network grounding resistance tester can test (4 Ω), water and fire power plants, microwave station Ω (10), the lightning rod (10 Ω) multi-purpose machine, adopted the new variable frequency ac power, and adopts the microcomputer processing control and signal processing, good solve the anti-interference problem in the process of test, simplifies the test process, The precision and accuracy of test results are improved, and the labor intensity and test cost of test personnel are greatly reduced.
Ground resistance tester has three pole measurement and four pole measurement, here guodian zhongxing divided into two explanations, we first look at the large ground network grounding resistance tester three pole measurement.
Note: The measuring mode on the instrument panel indicates that the switch points to the three-pole method when the earth grid grounding resistance tester is measured. The test connections of the three wires are respectively current pole pile, voltage pole pile and ground grid connection pile.
Next is a large grid grounding resistance tester of the quadrupole measurement
Note: When the earth network grounding resistance tester is measured by the quadrupole method, the measurement mode on the instrument panel indicates that the switch points to the quadrupole method. The two connecting lines are respectively connected to the voltage pole 2 and the two terminals of the earth network from the ground pile of the earth network, and then the test is carried out according to the measurement operation steps.
