All engineers know resistance is usually bad news. It generates heat. It reduces efficiency. It wears out components and cuts operational lifetimes. However, resistance is not the only kind of ...

With Megger’s new test van, it is now possible to carry out a full range of tests on power transformers quickly and conveniently at any location that can be reached by road. This means that ...

Test engineers struggle to find the optimum balance between printed-circuit-board (PCB) cost and test coverage. Low coverage leads to excessive field returns, warranty replacements, and even lawsuits.

Inductors and transformers serve key roles in switch-mode power supplies. Ensuring they perform as expected requires thorough in-circuit measurements performed under operating conditions. Here’s what ...
