6.4 Polarization Index (PI) and Absorption Ratio (DAR)

The Polarization Index (PI) and Absorption Ratio (DAR) are critical for assessing the quality and aging problems of insulation in electrical equipment.

• DAR (Dielectric Absorption Ratio): Ratio of insulation resistance at 60 seconds to insulation resistance at 30 seconds.
• PI (Polarization Index): Ratio of insulation resistance at 10 minutes to insulation resistance at 1 minute.

The MH13 can automatically compute DAR and PI. To perform these tests:

1. Set up the insulation resistance test as described in Section 6.2.
2. فشار ورکړئ 'PI/DAR' button.
3. فشار ورکړئ 'ټیسټ' button and hold it for the duration of the test (e.g., 10 minutes for PI). The device will automatically record the necessary resistance values at 1 minute and 10 minutes.
4. The calculated PI and DAR values will be displayed. Refer to the judgment standard table for interpretation.
