AEMC's digital ground resistance tester Model 6470 performs grounding resistance, earth-coupling measurement, soil resistivity, and bonding tests with a measuring range from 0.01 ohm to 99,000 ohms.

For electrical workers, installing a standard grounding system is almost an afterthought — drive two ground rods and you're done. But this practice is inadequate for today's demanding applications ...

Insulation failure is the root cause of many electrical conductors and equipment failures. When insulation fails, not only can equipment be damaged, but fire and shock can also result. Ideally, when ...

In the second part of this series on the highs and lows of resistance measurements, I illustrated the differences between two-wire and four-wire resistance ...
