Hands down — without a doubt, one of the most universally searched topics on EC&M ’s website from a historical perspective is “insulation resistance testing.” As a result, some of our most popular ...

Insulation failure is the root cause of many electrical conductors and equipment failures. When insulation fails, not only can equipment be damaged, but fire and shock can also result. Ideally, when ...

In some applications, O-rings also play roles in electrical insulation. A simple test is set up to study the electrical resistance across an O-ring seal in a conductive fluid environment: O-rings were ...
