How to Measure Insulation Resistance: A Comprehensive Guide
You'll need either a megohmmeter (traditional hand-cranked type) or digital insulation tester. For most low-voltage systems (≤1kV), a 500V-1000V device works best. High-voltage equipment (>1kV) requires 2500V models. Did you know? Some advanced testers can automatically calculate polarization index and dielectric absorption ratio for deeper analysis.
