IEC Insulation Testing Standards Explained: A Practical Guide

If you work with electrical equipment internationally, IEC standards govern how you test insulation. But the IEC catalog has dozens of standards that mention insulation testing — and figuring out which one applies to your equipment can be confusing. This guide cuts through the noise. I’ll cover the IEC standards you actually need for insulation testing, with the… Read More: IEC Insulation Testing Standards Explained: A Practical Guide »

Polarization Index Test: What It Is, How to Do It, and What the Results Mean

The polarization index test is the most reliable way to assess insulation condition on motors, generators, and other rotating machinery. It goes deeper than a standard 60-second megger reading and gives you a result that’s independent of temperature and equipment size. If you only have time for one insulation test on a critical motor, make it the PI… Read More: Polarization Index Test: What It Is, How to Do It,… »

Megger vs Hi-Pot: What’s the Difference?

Megger testing and hi-pot testing both involve applying high voltage to insulation. Both measure how current behaves through that insulation. And both help you find problems before they cause failures. But they’re not the same test. They serve different purposes, use different voltage levels, and are used at different stages of an equipment’s life. Mixing them up —… Read More: Megger vs Hi-Pot: What’s the Difference? »
