The Insulation Resistance (IR) test is a qualitative test that indicates the effectiveness of a product's electrical insulation.
Applications include cables, transformers, motors/generators, circuit breakers and bushings.
The IR test is ideal for measuring and recording long term stability of insulation over time, a process known as trending.
IR tests are temperature dependent and require adjustment to a reference temperature.
Storage models offer a temperature recording option.
