Insulation Resistance Test Limits Motor at Annie Burress blog

Insulation Resistance Test Limits Motor. For example, a motor rated at 2,400 volts. “per csa c392 the resistance unbalance limit for random windings should be 2% from the average, and 1% from the average for form coil. Ground insulation test of a motor. Determine if a motor is good. Insulation resistance should be approximately one megohm for each 1,000 volts of operating voltage, with a minimum value of one megohm. This test provides a quantifiable measure of the insulation resistance, typically expressed in hundreds of megaohms, or even gigaohms. How is ir testing done, in view of the fact that at least 80% of electrical maintenance and testing involves evaluating insulation integrity? Dc voltage of 500 or 1000 v is applied between the windings and the ground of the motor. Insulation resistance should be approximately one megohm for each 1,000 volts of operating voltage, with a minimum value of one. The insulation resistance test is a good, basic test, but it has its limits. This is how the test works: The rule may be stated:
