Why Are 2-Pole Motors More Prone To Phase-To-Phase Insulation Problems?
Phase-to-phase insulation fault is a unique fault feature of three-phase motors, and it is a problem of insulation breakdown between phases of the motor windings. From theoretical analysis, the probability of phase-to-phase insulation failures in multi-pole motors is higher, but from the actual fault analysis, it can be found that the problem of phase-to-phase insulation…
