In our previous issue, we described time-resistance and dielectric absorption ratio tests. Two other useful insulation resistance tests are the short time and step voltage tests In our previous issue, ...

In a perfect world, electrical insulation would allow no current to flow through it. Unfortunately, several factors can — and will — result in the deterioration and ultimate failure of electrical ...

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 ...

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 ...
