The present disclosure relates to a method of determining an electro- mechanical fault condition in a synchronous machine having a stator and a rotor, and an exciter. The method comprises a) obtaining an exciter current signal which is a measurement of an exciter current through stationary windings of the exciter, b) transforming the exciter current signal to obtain an exciter current frequency spectrum, and c) determining whether an electro-mechanical fault condition is present, and a type of the electro- mechanical fault condition, based on harmonic content related to the stator frequency of the stator, of the exciter current frequency spectrum. This disclosure further relates to a computer program product and to a synchronous machine electro-mechanical fault condition monitoring system. |
