Measuring the electrical resistance (ohms) of motors, compressors, and other electrical devices in HVAC systems may seem straightforward. But when the measurements of zero (0) or “OL” (overload) come ...

Insulation failure is a leading cause of electrical fires and system downtime, often occurring silently before any visible ...

Acceptance test reports can tell you the condition of your cables when they were installed, but they tell you nothing about the present condition. Startup alone can radically change the data ...

The new dual-purpose instrument combines high-voltage insulation testing up to 20 GΩ with comprehensive electrical measurement capabilities for field electricians.

In the second part of this series on the highs and lows of resistance measurements, I illustrated the differences between two-wire and four-wire resistance measurements on an actual low ohmic sample ...

Most design engineers take wire for granted and don’t give much thought to its basic wire-covering insulation. And why should they? In most cases, the insulation fulfills its role of preventing bare ...

Vitrek, a US-based manufacturer of high-precision test and measurement equipment, offers the 95X Series hipot tester with 100 pico-amp leakage current resolution for detecting micro-level insulation ...
