Abstract
A method and apparatus for detecting interruptions of continuity in a circuit is provided. The method includes transmitting a signal through a brush contacting a conductive band of a slipring, wherein the brush and the slipring have a relative motion. The apparatus is configured to determine a circuit interruption using a plurality of parameters of the signal transmitted through the brush and the slipring, and provide an indication of an interruption when the parameters of the signal transmitted through the brush and slipring are indicative of a circuit interruption.
