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 ...

Hands down — without a doubt, one of the most universally searched topics on EC&M’s website from a historical perspective is “insulation resistance testing.” As a result, some of our most popular ...

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 ...

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 safety testing has been around for almost a century, and safety agencies have been testing and certifying products for almost as long. Electrical and electronic products have changed ...

Handheld insulation testers in Megger’s MIT400/2 series offer a user-variable range that allows any intermediate test voltage from 10 V to 1000 V in 1-V steps. Replacing the original MIT400 series, ...

Engineers know there is a problem with premature failure of motors controlled with A-S drives. Now there is a new magnet wire insulation that may solve the problem without any change in motor design.
