5 and 10 kV DC Insulation Resistance Testers
Technical sheet
/ Standards
IEC 61010-1, CAT IV 600 V
/ Use

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.
