Beschreibung
Zusammenfassung:	A method for operating a multi-phase generator, and An arrangement for a multi-phase generator comprising a stator with a plurality of phases, each of the phases of the stator comprising a phase winding (W) having at least two phase winding circuits (C1, C2), the arrangement comprising switching means (S1, S2, S3) configured to connect, in a first winding configuration, in each of the phases of the stator all of the at least two phase winding circuits(C1, C2) of the phase of the stator electrically in parallel with each other, and connect, in a second winding configuration, in each of the phases of the stator at least two of the at least two phase winding circuits of the phase of the stator electrically in series with each other, and control means (100) configured to control the switching means (Si, S2, S3) from the first winding configuration to the second winding configuration in response to a detected predetermined fault condition.
