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 measurements on an actual low ohmic sample ...

When a voltage is applied to a material or device,current will flow through it. How much current will flow is based on theresistance that the material applies to a circuit. The resistance of a ...

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 ...

Megger now offers a digital low resistance ohmmeter that can deliver reliable results when using long test leads. The DLRO2, a 2 Amp handheld tester, is ideal for use in production line testing and ...

HVAC distributor cfm Distributors recently developed a list of items to test and/or questions to ask when dealing with sites that have experienced multiple failed compressors. The first step consists ...
