Abstract
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.
