INSULATION RESISTANCE
Insulation Resistance is the resistance offered by insulator separating two electrodes. The value determines quality of insulation.
POLARIZATION INDEX
The ratio of the ten-minute to the one-minute measurement is known as the Polarization Index. In general, a high ratio is indicative of 'good' insulation.
DIELECTRIC ABSORPTION
Carrying out a 10-15 minute test will yield some meaningful information. Clean, dry insulation will show an increasing resistance reaching a final steady-state level, after 10 to 15 minutes. Wet or dirty insulation will reach a steady state value much sooner.
