Insulation Resistance Test – I

An insulation resistance test is one of the tests required by electrical safety testing standards. The test measures the insulation resistance of the Device Under Test (DUT), while phase and neutral conductors are short circuited together.

Why conduct an insulation resistance test?

Quanti measures insulation resistance in electrical systems and in equipment such as electrical machines, household appliances, transformers, cables, power supplies, and so on. Once the voltage reaches the selected value, it is maintained at that value for a brief period (typically up to 5 seconds), after which the resistance value is measured.

Measuring range is from 0.5MΩ to 50GΩ with adjustable voltage 50…1000Vdc.
