Such asymmetry may occur in machines with unbalanced phase windings and in power supply systems when faults occur; the usual method of dealing with asymmetry is described in section 3.2.12. Attention here is confined to the basic symmetric cases. 3.2.11.1 Phase interlinkage While individual phase ...
