The Broadcom optical point sensor with self-supervision functionality. The light that meets the point sensor is captured and fed into a plastic optical fiber (POF). The self-supervision functionality is achieved by an in-built coupling between two fibers. The special POF-based sensor design allows the system engineer to avoid any galvanic contact between the arc flash area and the detection electronics The point sensor consists of two parts i.e, the sensor head and the connector. Both sensor head and connector are part of Broadcom’s comprehensive arc flash detection portfolio. In combination with Broadcom’s sensor transceiver, they are intended to be used for the detection of arc flash events in electrical power grids.
