Small and large disturbances in power system may sometimes lead to sustained oscillation in three-phase power, often termed as ‘power swing’ in the literature. Power swing is a balanced phenomenon and may be indistinguishable from a three-phase fault. Transmission lines being protected by distance relays may be incorrectly de-energized because of a power swing. So, three-phase faults should be discriminated
