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.
