Hipot Testers Explained: AC vs DC, Withstand vs Breakdown, Safety Specs

A hipot tester applies a voltage well above the equipment’s rated operating voltage and watches what happens. If the insulation holds, the equipment passes. If the insulation breaks down, the equipment fails. This sounds simple, but the practical implementation is full of decisions that affect what you can detect, what you can damage, and what your test results… Read More: Hipot Testers Explained: AC vs DC, Withstand vs Breakdown, Safety… »

Safety Procedures for Insulation Testing: A Field Engineer’s Checklist

Insulation testing involves applying high voltage to equipment. The megger on your belt can output 500V, 1,000V, 2,500V, or even 10,000V DC. That’s enough to injure or kill. But the real danger often isn’t the megger itself — it’s the stored energy in the equipment you just tested. A long cable charged to 5,000V DC during a 10-minute… Read More: Safety Procedures for Insulation Testing: A Field Engineer’s Checklist »

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? »
