摘要
A method is provided for monitoring and/or analysis of electrical machines during operation. An electrical machine has at least one generator with a shaft, an exciter system and drive device that drives the shaft. In this case, a first signal, which describes a voltage across a rotor winding, and a second signal, which describes a current flowing through the rotor winding, are measured simultaneously. The two signals are supplied to an analysis unit. The signals are split into individual frequency components in the analysis unit. The impedance of the rotor winding is then determined in order to identify fault states in the electrical machine.
