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 ...

Insulation resistance testers, often called megohmmeters, are fundamental tools for preventive maintenance, used to assess ...

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 ...

The new S1-552 and S1-1052 insulation resistance testers from Megger are designed to assist the user with the testing and maintenance of high-voltage equipment. Each instrument’s control panel is ...

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, ...

Most design engineers take wire for granted and don’t give much thought to its basic wire-covering insulation. And why should they? In most cases, the insulation fulfills its role of preventing bare ...

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, ...

Railways require safe, reliable power systems to support signals, points and communications infrastructure. Trackside equipment must be protected from failure, and with thousands of miles of track to ...
