Method for detecting an electrical fault in a generator assemblage, and means for implementation thereof

A generator regulator of a generator, which is for a generator assemblage having a rectifier having rectifier elements, comprising:

• a comparator to compare at least one AC voltage present at at least one AC-voltage-side terminal of a rectifier with at least one DC voltage present at a DC-voltage-side terminal of the rectifier;
• and
• a computation unit with which the at least one parameter is determinable based on the comparison;
• wherein, in the context of at least one excitation current value of an excitation current through an excitation winding of the generator, the at least one parameter is determined that corresponds to a current conduction time proportion of at least one of the rectifier elements, and
• wherein it is determined that an electrical fault exists if the at least one parameter deviates in more than predetermined fashion from an associated expected value.

A computer readable medium having a computer program, which is executable by a processor, comprising:

• a program code arrangement having program for identifying an electrical fault in a generator assemblage, the generator assemblage including a generator having a generator regulator and a rectifier having rectifier elements, by performing the following:
• ascertaining, in the context of at least one excitation current value of an excitation current through an excitation winding of the generator, at least one respective parameter that corresponds to a current conduction time proportion of at least one of the rectifier elements;
• and
• determining that an electrical fault exists if the at least one parameter deviates in more than predetermined fashion from an associated expected value.
