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 ...

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. Short time. This is ...

The new S1-552 and S1-1052 insulation resistance testers from Megger are designed to assist the user with the testing and maintenance of high-voltage equipment. Each instrument’s control panel is ...

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 ...

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 ...

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 ...
