Product Details

WUHAN HUAYING HYDW III Ground 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 4O, power station, microwave station 10O, lightning rod 10O and so on.

HYDW-III survey meter for grounding resistance of large ground grids is an all-purpose tester with electrical source of non-power frequency, the tester can measure the grounding resistance of substation (4O), thermal power plant\hydropower plant, microwave station (10O), lighting rod etc. Microcomputer is adopted to control HYDW-III survey meter and process testing datum, which eliminates interferences from the testing process, simplifies operation programs of testing, enhances precision and veracity of measuring, and reduces the cost of labor and test.
