- Abstract
In this letter, we present a new single phase-to-ground fault feeder selector for a resonant grounded distribution system based on mathematical morphology. A combined morphological filter, which is the average of open–closing and close–opening, is employed to extract the transient component and decaying DC component from the zero-sequence current signal of each feeder. Afterward, two indices are introduced to measure these components and to distinguish the fault feeder from healthy feeders. Simulation studies are conducted using PSCAD/EMTDC, and the results verify the effectiveness of the proposed method.
