www.aemc.comThree-Phase Dual-Voltage Motor Insulation Resistance Testing Three-phase dual-voltage motors are used for most day-to-day operations in today’s industrial plants. These motors run conveyor belts, pumps, fans, and many other applications. Motors are susceptible to the gradual failure of their insulation resistance. The primary causes of insulation
Understanding Insulation Resistance Testing
www.aemc.cominsulation looks ok. Time-resistance tests on large rotating electrical machin-ery – especially with high operating voltage – require high insulation resistance ranges and a very constant test voltage. A heavy-duty megohmmeter serves this need. Similarly, such an instrument is better adapted for cables, bushings,
