Features:
- High Test Voltage: It can generate test voltages up to 5000V (5kV), with selectable fixed voltages (500V, 1000V, 2500V, 5000V) and a programmable variable voltage from 40V to 5100V. This wide range makes it suitable for testing a broad spectrum of electrical equipment.
- Wide Insulation Resistance Range: It measures insulation resistance from 30 kΩ up to an impressive 10 TΩ (Teraohms), allowing for accurate assessment of both healthy and degraded insulation.
- Automatic Calculation of Diagnostic Ratios: A key differentiator is its ability to automatically calculate and display critical diagnostic ratios:
- Dielectric Absorption Ratio (DAR): (1-minute reading / 30-second reading) – Helps detect moisture and contaminants in insulation.
- Polarization Index (PI): (10-minute reading / 1-minute reading) – Provides a long-term assessment of insulation condition and dryness. User-programmable PI ratio times are also available.
- Dielectric Discharge (DD): Measures current after a minute of discharge relative to test voltage and capacitance, indicating the presence of multiple layers of insulation or issues like delamination.
