Systems and methods are disclosed to monitor real-time digital data for degradation. In one embodiment, an intelligent electronic device ('IED') in an electric power system may include an interface to receive a stream of digital data, the stream of digital data comprising a plurality of data frames. A protective action subsystem may monitor the sampled digital data and implement a protective action based on the stream of sampled digital data. A digital data degradation detection subsystem may analyze a plurality of digital metrics associated with the plurality of data frames and make a determination regarding degradation of a communication channel based on whether the plurality of digital metrics fails at least one threshold. In response to the determination, the digital data degradation detection subsystem may implement a response to the determination that the plurality of digital metrics fails at least one threshold.

Real-time digital data degradation detection

The present disclosure pertains to systems and methods to share data in a point-to-point system. In one embodiment, a system to share point-to-point information may be used in an electric power system, and the system may include a communication interface to communicate using a point-to-point protocol using at least a first port and a second port. A point-to-point information sharing subsystem may receive an indication that point-to-point information received on the first port is to be shared on the second port and may configure the second port to share point-to-point information received on the first port. In some embodiments, a delay associated with the communication link may be added to the shared point-to-point information prior to transmission.
