Abstract
An overcurrent display device is described which is suspended directly from a distribution cable for locating the spots of earthing, short-circuiting or other accidents in a distribution line system and is adapted to display the passage of the transient overcurrent due to such accidents through the cable for a predetermined time and to be restored to the original state before the display of the overcurrent condition. The device consists of an overcurrent sensing circuit, a drive unit including a drive element driven by the sensing circuit and a display unit actuated by the drive unit and adapted to achieve a display operation.
