Diagnostic Test Methods: DAR and PI

Dielectric Absorption Ratio (DAR) Test

The Dielectric Absorption Ratio (DAR) is a crucial diagnostic method for assessing insulation condition. By measuring the ratio of insulation resistance at two specific time intervals (typically 30 and 60 seconds), it provides rapid insights into insulation health.

Key Diagnostic Capabilities:
  • Quickly detect moisture contamination
  • Identify early signs of insulation degradation
  • Evaluate polarization characteristics of insulating materials
  • Provide fast assessment of electrical equipment reliability

Polarization Index (PI) Test

The Polarization Index (PI) offers a more comprehensive evaluation of insulation condition by comparing insulation resistance at 10 minutes to the resistance at 1 minute after applying a test voltage.

Critical Applications:
  • Comprehensive long-term insulation health assessment
  • Detecting gradual insulation deterioration
  • Identifying complex insulation defects
  • In-depth reliability analysis of electrical systems
PI Test Interpretation:
  • PI > 2: Indicates good insulation condition
  • PI 1-2: Suggests potential insulation issues
  • PI < 1: Indicates significant insulation degradation

Professional Workflow Enhancement

The UT505B is more than just a measurement tool—it's a comprehensive diagnostic system that:

  • Provides advanced safety features
  • Delivers precise, actionable electrical system insights
  • Supports sophisticated maintenance strategies
  • Enables detailed performance documentation
