Appendix A Winding Faults
For initial determination of winding faults, refer to the following figures. These wave patterns
are typically seen for three phase wye-connected, lap-wound induction stators. They provide
a reference for associating a characteristic wave pattern with a fault type.
Note:
Variation from these wave patterns is to be expected. Do not consider these wave
patterns as absolute. Remember, that due to the variety of motor windings and connections
that exist, each motor winding will have its own signature wave pattern. Memorization or
exact matches to the following patterns is not necessary when testing.
