Abstract
A blown fuse proximity sensing deviceis for use with a rectifying wheelof a type including rectifying diodesand associated fuses. Each fusemay include a housing, a fuse elementcarried by the housing, and a pop-out indicatormovable between a normal position and a popped-out position. In the popped-out position, the indicatorextends outwardly from the housing responsive to failure of the fuse element. At least one stationary proximity sensoris mounted adjacent the rectifying wheelfor sensing positions of the pop-out indicatorswithout contact therewith during rotation of the rectifying wheel to thereby sense at least one blown fuse. The sensing devicemay also include a local display, and a controllerconnected to the stationary proximity sensorfor generating an indication of a blown fuse on the local display. The controllermay also generate at least one remote output, such as to be monitored by other plant control equipment.
