Abstract: A method for generating corrected measured current in an Intelligent Electronic Device (IED) that is a true representation of primary current in an electrical network is disclosed. The method uses regression and a first threshold on measured sampled values from CT to detect a deviation instance that indicates a possibility of saturation. Wavelet and second threshold based detection of instances of saturation is then done. Then a regression based correction that uses a dynamic correction factor is implemented in real time to obtain corrected sampled values i.e. corrected measured current. Ending of correction is done based upon a predetermined selection criterion, The generated corrected measured current is used for protection and control functions in the IED. A CT output re-generation module as a functional module in the IED for implementing the method as described above is also disclosed.

Abstract: A method for operating a time-sensitive network, TSN, having a first, high-importance segment and a second, low-importance segment, includes remapping, using TSN per-port priority regeneration, priority labels attached to data streams received on the first port and the second port to updated priority labels; splitting the data streams into a “preempting” class and a “preemptable” class based on a mapping from updated priority labels to classes; and forwarding the data streams from a border network element to at least one next-hop network element. When congestion is present on a link to the next-hop network element, the forwarding of “preempting” data streams takes precedence over the forwarding of “preemptable” data streams.
