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 measurements on an actual low ohmic sample ...

Resistance standards are incredibly useful, but like so many precision references they require regular calibration, ...

Insulation resistance testing is one of the most useful predictive maintenance tests available. This test gives insight into the integrity of insulation. The higher the resistance across the ...

The types of insulation used in rotating machines have continued to evolve and precipitate changes to insulation resistance testing since 1974 when IEEE Std. 43, Recommended Practice for Testing ...

AEMC’s rugged, digital ground resistance tester Model 6470 performs grounding resistance, earth coupling measurement, soil resistivity and bonding tests. This direct reading tester measures from 0.01 ...

To be fully in conformance with the most modern testing requirements, Megger offers a family of insulation testers at voltages above 1 kV. July 20, 2009 2 min read To be fully in conformance with the ...

In the first part of this series on the highs and lows of resistance measurements, I discussed the basic principles for making two- and 4-wire resistance measurements for measuring resistances of less ...
