For Dielectric Absorption Test Equipment Rely On Protec

The ratio of two time-resistance readings (such as a 60-second reading divided by a 30-second reading) is called a dielectric absorption ratio. It is useful in recording information about insulation. If the ratio is a 10-minute reading divided by a 1-minute reading, the value is called the polarization index.

With hand-cranked instruments, it is easier to run the test for only 60 seconds, taking the first reading at 30 seconds. When using line-operated instrument, you will get best results by running the test 10 minutes, taking readings at 1- and at 10-minutes, to get the polarization index.
