ABSTRACT:
A cooled resistor pack for a dynamoelectric machine wherein cooling water is passed through ducts in a conductive block and plurality of connectors are mechanically attached to the conductive block but electrically insulated therefrom and nichrome wires of varying length and varying in number electrically join the connectors to the conductive block and individually insulated brush segments, which have individual strands and the brush segments are connected to separate connectors in such a manner that the resistance between the brush segments and the block decreases from the trailing end segments to the leading end segments of the brush.
