Abstract: The present disclosure relates to systems and methods for detection of a failed communication link and rerouting network traffic around the failure. One embodiment of a system consistent with the present disclosure may comprise a communication subsystem in communication with the data network and configured to transmit information to a recipient. The system may also include a confirmatory signal subsystem configured to generate a confirmatory signal. The confirmatory signal may be inserted into a stream of data to be transmitted to the recipient through a first communication path. Upon detection of a disruption in the confirmatory signal, a failover subsystem configured to reroute the stream of network data to be transmitted to the recipient through a second communication path. The second communication path may comprise one or more physical connections in the network that are distinct from the first communication path.

Abstract: The present disclosure pertains to systems and methods for monitoring electrical arc events in an electric power system. In one embodiment, a system may comprise an arc flash detection (AFD) unit to detect electromagnetic radiation generated by an electrical arc event, a primary protection relay to generate measurements of an electric current, and an integrator. In various embodiments, the integrator may comprise a communication port to receive the detection of the electrical arc event and the measurements of the electric current. The integrator may also comprise a processing subsystem to validate the detection of the electrical arc and generate protective actions to interrupt the flow of the current to the electrical arc event.
