Abstract
A method for monitoring the operation of an electrical assembly having a plurality of coils disposed electrically in a parallel circuit, includes detecting, off-power, the voltage at each coil by using a tap on a winding, determining the AC component of the detected voltage for each coil, determining the mean value of the voltage at the coils, evaluating the determined AC component for each coil with respect to the determined mean voltage, while applying a weighting, and generating a signal if a weighted deviation of a value describing the AC component of a detected voltage in a coil from a value describing the mean voltage exceeds a specified limiting value. An electrical assembly and a method for operating the assembly are also provided.
