Insulation resistance testers, often called megohmmeters, are fundamental tools for preventive maintenance, used to assess ...

Contact resistance, or CRES, is one of those problems that most engineers prefer not to think about until it’s staring them in the face. For years, it could be managed quietly with routine probe card ...

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 ...

When a voltage is applied to a material or device,current will flow through it. How much current will flow is based on theresistance that the material applies to a circuit. The resistance of a ...

Hipot, insulation-resistance (IR), ground-resistance, and ground-bond (GB) testing are all critical elements of measuring electrical safety across various industries. Thankfully, technology has ...

Electrical safety testers—often referred to as “hipot” testers—are an integral part of electrical and electronic equipment manufacturing. Hipot testers get their name from the high-potential (high ...

In performing service and troubleshooting on heat pump systems, there are various electrical components to be checked. The following provides information to aid in inspecting and servicing these ...

In this interview, industry expert Jason Chonko shares practical strategies for overcoming common challenges in high-resistance and low-signal electrical measurements by addressing noise, grounding, ...
