Abstract: Disclosed herein are systems for determining a broken conductor condition in a multiple-phase electric power delivery system. It has been observed that broken conductors pose a safety concern when occurring in the presence of people or vulnerable environmental conditions. Broken conductor conditions disclosed herein may be used to detect and trip the phase with the broken conductor, thus reducing or even eliminating the safety risk. Further, a distance to the opening may be determined.

Abstract: Systems and methods described herein monitor real-time digital data for degradation. A merging unit may measure electrical parameters in an electric power system using a sensor component and may generate a stream of digital data representing measured electrical parameters. The merging unit may transmit the stream of digital data representing measured electrical parameters and receive a plurality of data frames using an interface. A digital data degradation detection subsystem may analyze a plurality of digital metrics associated with the plurality of data frames and make a determination of whether a subset of the plurality of data frames satisfies the plurality of digital metrics, and the subset of the plurality of data frames fails at least one of the plurality of digital metrics. The merging unit may implement a response when the subset of the plurality of data frames fails at least one of the plurality of digital metrics.

Abstract: 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.
