Web10 mrt. 2024 · How to perform a motor winding resistance test A motor winding test is an important test as it checks the condition of each winding on the motor. It checks that … WebIt is also necessary to check windings for a phase-to-phase short in a similar manner. Separate the motor leads, and connect the megger from the Lead #1 to Lead #2. Likewise, check from Lead #2 to Lead #3, and from Lead #3 to Lead #1. These test results should meet the same minimum value as expected for phase to ground measure-ments.
