Abstract: Provided is a system and method to automatically identify metering constraints of one or more IEDs in an electrical system, which include capturing at least one energy-related waveform using at least one of the IEDs in the electrical system, and processing electrical measurement data from, or derived from, the at least one energy-related waveform to identify anomalous characteristics in the electrical system. In response to identifying anomalous characteristics in the electrical measurement data, an event constraint model is built based on or by using the identified anomalous characteristics. Once built, the event constraint model is analyzed to determine if the at least one energy-related waveform is being adequately captured by the at least one of the IEDs. In response to determining the at least one energy-related waveform is not adequately captured, one or more actions may be taken to address the capturing inadequacy.

Abstract: A method for automatically assessing event recovery in an electrical system includes processing energy-related data from or derived from at least one energy-related signal captured by at least one Intelligent Electronic Device (IED) in the electrical system to identify at least one occurrence of an event in the electrical system. In accordance with some embodiments of this disclosure, the energy-related data associated with the at least one identified event occurrence may be analyzed to determine impact of the event on loads and/or zones associated with the electrical system, and whether recovery from the event has been initiated or started for at least one of the loads and/or zones impacted by the event. At least one load, load type, and/or zone recovering from the event and a recovery profile for the at least one load, load type, and/or zone may be determined.

Abstract: A method to automatically optimize waveform captures from an electrical system includes capturing at least one energy-related waveform using at least one Intelligent Electronic Device (IED) in the electrical system. The at least one captured energy-related waveform is analyzed to determine if the at least one captured energy-related waveform is capable of being compressed, while maintaining relevant attributes for characterization, analysis and/or other use. In response to determining the at least one captured energy-related waveform is capable of being compressed, while maintaining relevant attributes for characterization, analysis, and/or use, the at least one captured energy-related waveform may be compressed using at least one compression technique to generate at least one compressed energy-related waveform. One or more actions may be taken based on or using the at least one compressed energy-related waveform.

Abstract: Systems and methods for improving identification of issues associated with detecting anomalous conditions (e.g., electrical transient voltages) in electrical systems are disclosed herein. The anomalous conditions may be difficult to discern, for example, due to metering constraints of Intelligent Electronic Devices (IEDs) responsible for identifying the anomalous conditions in the electrical systems. In one aspect of this disclosure, a method to automatically identify metering constraints of one or more IEDs in an electrical system includes capturing at least one energy-related waveform using at least one of the IEDs in the electrical system, and processing electrical measurement data from, or derived from, the at least one energy-related waveform to identify anomalous characteristics in the electrical system. The anomalous characteristics may be indicative of an anomalous condition in the electrical system, for example.
