  • Patent number: 9435835
    Abstract: The present disclosure provides systems and methods for validating electric power delivery monitoring systems, including, but not limited to, current transformers (CTs) and voltage potential transformers (PTs). According to various embodiments, a first IED monitors a portion of an electric power delivery system via one or more CTs and/or PTs. A second IED monitors the portion of the electric power delivery system via one or more additional CTs and/or PTs. Each IED may generate an event report, containing measurement data, associated with each respective measurement equipment. A validation module may compare the event reports in order to validate that the IEDs and/or the underlying measurement equipment are functioning correctly. According to various embodiments, the validation module may be configured to align the event reports from two IEDs using an event trigger common to both IEDs.

  • Patent number: 8797018
    Abstract: An apparatus and method for identifying the current and voltage phase and terminal for power system devices is described. In one aspect of the present invention, the respective current phase and terminal of two current terminals is identified based on a known phase and known phase angle associated with a third current terminal at the location of the electrical power system. In another aspect of the present invention, the voltage phase and terminal is identified based on a known phase and known phase angle associated with a third current terminal at the location of the electrical power system. In another aspect of the present invention, the respective voltage phase and terminal of three voltage terminals is identified based on known phase and known phase angles associated with first and second current terminals at the location of the electrical power system.
