Abstract
An arc detection assembly is provided and includes first and second conductors including first and second terminal ends, respectively, which are engageable to form an electrical connection and a temperature sensing system. The temperature sensing system includes a temperature sensor disposed in contact with one of the first and second terminal ends and configured to sense a temperature of the one of the first and second terminal ends and a temperature monitoring circuit. The temperature monitoring circuit is coupled to the temperature sensor and configured to determine when the temperature sensor senses an increase in temperature of the one of the first and second terminal ends and to determine whether the increase in temperature is indicative of an arcing condition of the electrical connection.

An arc detection assembly, comprising:
- multiple pairs of first and second conductors comprising first and second terminal ends, respectively, which are engageable to form multiple electrical connections;
- and
- a temperature sensing system comprising:
- temperature sensors each of which is respectively disposed in contact with one of the first and second terminal ends of each of the multiple electrical connections and configured to sense a temperature of the one of the first and second terminal ends;
- and
- a temperature monitoring circuit coupled to each of the temperature sensors and comprising a controller configured to determine when any of the temperature sensors senses an increase in temperature of the one of the first and second terminal ends and to determine whether the increase in temperature is indicative of an arcing condition of the corresponding one of the multiple electrical connections,
- wherein the temperature monitoring circuit further comprises cables, each of which is routed from a corresponding one of the multiple electrical connections and through each respective interior of each intervening one of the first conductors and through each respective interior of each intervening one of the second conductors to the controller and by which each of the temperature sensors of each of the multiple electrical connections and the controller are communicative.
