1. A temperature sensor for monitoring a temperature of a bolted connection of a bus bar, comprising:

  • a thermally conductive metallic housing having a metallic skirt portion with an opening through which to fit the skirt portion onto a portion of a bolted connection of a bus bar, the skirt portion of the housing being configured to be in thermal contact with the bolted connection when the skirt portion is fitted on the portion of the bolted connection of the bus bar; and

    a temperature transducer mounted externally on the metallic housing and in thermal contact with the housing, the temperature transducer configured to sense a temperature of the metallic housing relating to a temperature of the bolted connection and to provide sensor output signals on sensor wires externally connected to the temperature transducer, corresponding to the sensed temperature.
