ABSTRACT:
A method for decoupling a high-frequency error signal from a high-frequency electromagnetic field in a heavy electrical machine includes decoupling a high-frequency error signal with at least one temperature probe acting as an antenna and being associated with a stator carrying an electrical winding. In a heavy electrical machine having a stator carrying an electrical winding, an apparatus for decoupling a high-frequency error signal from a high-frequency electromagnetic field includes at least one temperature probe being disposed in the stator for generating a low-frequency temperature signal. The at least one temperature probe has connecting lines leading out of the stator. A diplexer decouples the error signal from the temperature signal. The diplexer has an input to which the connecting lines are connected, a first output at which the temperature signal is furnished, and a second output at which the error signal is furnished.
