[0002] Insulation resistance is an important indicator for evaluating equipment safety and predicting potential failures in electrical equipment, wires, cables, transformers, motors, generators, electronic equipment, and other power systems. Low insulation resistance may indicate equipment aging, damage, moisture, contamination, or design flaws, which can lead to current leakage, overheating, short circuits, fire, and even electric shock hazards.
