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 ...

Insulation failure is a leading cause of electrical fires and system downtime, often occurring silently before any visible signs appear. Regular insulation resistance testing helps detect early ...

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, ...

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, Megger’s new S1-1568 test sets combine noise rejection ...

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 ...

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 ...

Although the term ‘Iron Curtain’ from the Cold War brings to mind something like the Berlin Wall and its forbidding No Man’s Land, there was still active trade between the Soviet Union and the West.
