Infrared - Condition Monitoring

High Resistance can Develop in Crimped-on Connections

When inspecting electrical equipment with IR, there are obviously many connection points where high resistance can develop, resulting in abnormal h

Electric Motor Testing (EMT)

Resistance, Quite Simply, is Opposition to Current Flow

Monitoring motor circuit resistance is of critical importance.

Seeing Sharp Reflections when Inspecting Windows

In building thermography, many materials appear thermally the way that you’d expect them to. Glass is the one exception.

Electric Motor Testing (EMT)

Using Multiple Data Sets for Fault Localization

Having a motor test instrument does not mean that you will be able to diagnose problems.  Motor test instruments provide data that correlates

Moisture Conditions may have Thermal Effects Beyond the Obvious

When it’s wet it’s cold, right? This is an easy assumption to make. When we consider moisture, we often think of evaporation.

Electric Motor Testing (EMT)

Capacitance to Ground Testing can be Extremely Valuable

Capacitance to ground measurement is fundamentally an early warning system that provides an indication that your motor’s insulation is on a path to
