Hengfeng ground resistance tester A large number of on-site tests and user usage indicate that when the grounding grid is tested under the harsh electromagnetic environment of the running substation, the measured data of the grounding impedance tester of the special frequency ground network are accurate and repeatable. It is an ideal instrument for the measurement of the characteristic parameters of large and medium grounding grids.

Features

3. Double frequency conversion,strong anti-interference ability. The instrument adopts the method of different frequency measurement, and with modern software and hardware filtering technology, the instrument has high anti-interference performance, and the test data is stable and reliable.

6. Transmission tower vector shunt function.The instrument automatically subtracts the current that is transferred by the tower to calculate more accurate test results.

9. Simple wiring ,no high current cable is needed.
