Passage:
Before energizing heavy three-phase industrial motors that have remained idle in unheated storage facilities over the winter, technicians perform an insulation resistance check with a megohmmeter. If the reading falls below the standard operating threshold, the motor is not immediately condemned as defective. Instead, low-voltage heating blankets or internal space heaters are energized for forty-eight hours to evaporate dampness. Only after the unit has thoroughly dried out is the resistance test repeated to verify whether the windings are genuinely ruined.
Evaluate whether the following statement is True or False based on the passage:
Moisture accumulation can cause an idle motor to fail an initial insulation test even when its electrical windings remain structurally intact.
