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 ...

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 ...

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 ...

Your client has asked that you perform hipot testing on your PCB and on the cable assemblies of your design. What are the three common hipot tests and what do they measure? This particular hipot test ...

The street scene shows damage caused by an explosion in a manhole as a result of gases generated by a low-voltage arcing fault. North America, according to statistics published by the IEEE Insulated ...

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 ...

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 ...
