Sometimes, an insulation resistance (IR) testing program is in place, yet a major cable failure still occurs. Because it doesn't seem to work, cutting back or eliminating the program appears to make ...

Insulation resistance testing is a simple yet critical preventive measure that can significantly lower your maintenance costs. You may be familiar with the role insulation resistance testing plays in ...

This article describes the testing results following routine performance assessment of an electrical motor both in its original state and after rebuilding it using products made by Zeus, such as the ...

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 ...

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 ...

Bringing the benefits of 15 kV DC insulation resistance testing to challenging environments such as HV transmission and distribution substations, Bringing the benefits of 15 kV DC insulation ...

Electrical safety testers—often referred to as “hipot” testers—are an integral part of electrical and electronic equipment manufacturing. Hipot testers get their name from the high-potential (high ...

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 ...
