Abstract
A switchgear cabinet (100) includes an equipment compartment (102), a bus compartment (104) and a cable compartment (106). The cabinet can employ a sensor(s) (190) to monitor conditions, such as arcing, in the bus or cable compartment. The cabinet also includes a retractable sensor system (150), which has a rack (160) and a slider (170). The rack is mounted in the cabinet, and the slider is configured to retain the sensor. The slider is movably engaged to the rack. The slider can slide in one direction toward a back of the bus or cable compartment to a racked-in position in which the sensor is located to sense arcing in the bus or cable compartment. The slider can slide in an opposite direction toward a front of the equipment compartment to a racked-out position in which the sensor is drawn into the equipment compartment.
