Abstract: It is possible to determine the types and values of stator and rotor errors in magnetic circuits in a synchronous machine by measuring the induced voltage (ui) for the terminals of measurement loops which can capture an image of the induction in the measurement gap, then by treating said signals.

Abstract: A generator having electronic circuit breakers as circuit breakers, whereby circuits comprising thyristors, IGBT elements and/or GTO thyristors are used, and whereby the circuit breakers are integrated into the generator, preferably in that the circuit breakers are distributed on parallel winding branches of the stator. Such power electronics can also be used for switching generators having a power above 50 MV with very short switching times of a few milliseconds.
