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 ...

Testing insulation is an important way to qualify a new installation. Testing also protects and prolongs the life of electrical systems and motors. Over the years, electrical systems are exposed to ...

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 ...

Electrical insulation begins to age and thus deteriorate as soon as it is made. Exposure to harsh environmental conditions, such as extreme temperatures, mechanical damage, and chemical vapors, ...

Megger’s new high-voltage insulation resistance testers (IRTs) offer versatility in a compact, rugged and light unit that weighs little more than half as much as its predecessors. Megger’s new ...

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.

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, ...
