Measurement of Insulation Resistance
What is Insulation Resistance Test or IR Test? The Insulation Resistance Test measures the Insulation resistance of a device under test, while phase and neutral
IR Test
Polarization Index Test and DAR Test
The polarization index test is a 10-minute to 1-minute ratio test of insulation resistance. Similarly, the DAR test is a 60-second to 30-second insulation resistance
