Routine offline and shop stage gate tests should include Phase-to-Phase Inductance measurements. Phase-to-Phase measurements can be useful for diagnosing a variety of situations:
Poor or incorrect rework such as reversed coil winding leads
Faults in power cables or main contacts in the power circuit
Air gap eccentricity problems
Shorted turns such as stator phase-to-phase and coil-to-coil
Rotor porosity and lamination damage
Broken/cracked rotor bars or end rings
