In Episode 27 of “EC&M Tech Talk,” Randy Barnett, a journeyman electrician, inspector, author, trainer, and electrical safety expert, reviews the purpose and methods used for measuring the quality of ...

To meet the requirements of your electrical safety testing applications, you can choose from a variety of instruments and systems that perform hipot, insulation-resistance (IR), ground-resistance, and ...

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 ...

A company named LEM introduces its Model LK60 clamp-on leakage-current meter for non-invasive checks of insulation resistance. Leakage current measurement can be used to assess the state of electrical ...

In response to the growing recognition of the benefits of 15 kV dc insulation testing, Megger has introduced two new instruments with 15 kV testing capabilities – the MIT1525 and the S1-1568.

The new S1 Series of 5-kV and 10-kV insulation resistance testers from Megger are designed specifically to assist the user with the testing and maintenance of high-voltage equipment. The new S1 Series ...

Because they are integral to a variety of common test applications, ensuring of high-Ω measurement accuracy can be critical High-resistance measurements are integral to a variety of test applications, ...

Measuring the electrical resistance (ohms) of motors, compressors, and other electrical devices in HVAC systems may seem straightforward. But when the measurements of zero (0) or “OL” (overload) come ...

Electrical resistivity is a basic property that quantifies a material’s opposition to current flow—it’s the reciprocal of conductivity. The resistivity of a material depends upon several factors, ...
