Cable Insulation Testing

Cable Insulation Testing

An Insulation Resistance test measures the total resistance of a product's insulation system. The test is usually performed as a quick check after a product is manufactured, installed or repaired. It is also a useful test to perform when doing preventative maintenance on a product over time. Changes in the insulation measurement can help to predict if a product such as a motor, cable or component is due to fail.

A Megohmmeter refers to an instrument whose meter is usually scaled to read in MΩ (millions of Ω's). An Insulation Resistance tester refers to an instrument that measures the resistance of a product's insulation system.
