Absorption Ratio and Polarization Index Standards:

• Absorption Ratio (DAR): Measures the insulation resistance ratio at 1 minute to that at 30 seconds.
• Polarization Index (PI): Measures the insulation resistance ratio at 10 minutes to that at 1 minute, helpful for determining moisture impact on insulation resistance.
• Essential for assessing the absorption and polarization processes in insulating materials under high voltage.
• Used in power systems to evaluate insulation quality, crucial for main transformers, cables, motors, etc.
