Gddw-III Large Earthing Resistance Tester

General introduction:
Supplied with the new type different frequency AC power supply, It adopts microprocessor to control and process signal, which solve problems of the interference between test lead wires. It is used to test grounding resistance in different places such as substation ground network(4Ω ), power station, microwave station(10Ω ), lightning rod(10Ω )and so on.
Application:
GDDW-III grounding resistance tester is applied to measure the grounding resistance in power station or generator station with non-power frequency. All test results could be printed by micro printer
