摘要： A method to identify phase is presented. The method includes obtaining electrical parameters at a node and a substation of an electrical grid, processing the electrical parameters of the node and the substation into processed electrical parameters comprising at least one of a voltage harmonic amplitude, a current harmonic amplitude, a geometric harmonic modulated signal, and a noise pattern. The method further includes comparing the processed electrical parameters from the node and the substation and identifying phase information of the node with respect to the substation.

摘要： A system for distributing electrical current to a plurality of loads includes a first sensor coupled to an input of a protection zone for measuring a first current entering the protection zone, wherein the protection zone includes at least a portion of an electrical distribution feeder. The system also includes a second sensor coupled to an output of the protection zone for measuring a second current exiting the protection zone, and a processor coupled to the first sensor and to the second sensor. The processor is programmed to receive measurements representative of the first current and the second current, and calculate a reactive current differential of the protection zone based on the first current and the second current. The processor is also programmed to compare the reactive current differential with a fault threshold, and generate an error notification if the reactive current differential is greater than the fault threshold.
