3A Strong Anti-interference Large-scale Grounding Grid Earth
Resistance Tester
Product introduction
ZXDW-3A Large-scale Grounding Grid Earth Resistance Tester applies to test frequency ground resistance, contact voltage, pace
voltage and earth electric resistivity. Can test substation
grounding grid (4Ω), fire and water electric power plants,
microwave stations (10Ω), lightning rod multi-purpose model (10Ω).
It adopts different frequency anti-jamming technique, can get the
data under 50Hz in strong interference circumstance. measured
current from 0~3A, which will not cause the electric potential of
the grounding device too high. It’s with strong anti-interference
ability, so no need power off during the test
