Abstract: Systems and methods may be used to assess network communications by generating one or more current communication parameters based on communications at an intelligent electronic device (IED) within an electric power delivery system. Network communications may be assessed by determining, at the IED, whether the communications fall within one or more thresholds for the current communication parameters.

Abstract: A trace data capture device has trace storage circuitry for storing trace data captured from a data processing apparatus. Detection circuitry detects source identifiers identifying which trace source generated the trace data. Output circuitry outputs to a diagnostic apparatus, independently from the trace data, source identifying data which indicates which source identifiers were detected for the trace data stored in at least a portion of the trace storage circuitry. By allowing the diagnostic apparatus to determine which source identifiers have been detected for which region of the memory, this can allow more targeted uploads of trace data, to reduce the time required for uploading the trace data and reduce the time to determine if data is not present for a particular source.

The insulation may provide a partial discharge inception voltage greater than approximately 1,000 volts and a dielectric strength greater than approximately 10,000 volts. Additionally, the insulation may be capable of withstanding a continuous operating temperature of approximately 220° C. without degradation. The insulation may include at least one base layer formed around an outer periphery of the conductor, and an extruded thermoplastic layer formed around the base layer. The extruded layer may include at least one of polyetheretherketone (PEEK) or polyaryletherketone (PAEK).

Abstract: A continuously transposed conductor (CTC) cable may include a plurality of electrically insulated strands arranged in two stacks with the plurality of strands successively transposed between the two stacks. Each strand may include a conductor and insulation formed at least partially around the conductor. Additionally, each strand may have a cross-sectional area that is less than approximately 0.0030 square inches. As a result, the CTC cable may be suitable for use in electrical devices relatively smaller than those associated with conventional CTC cables.
