A Lissajous Curve–Based Method for Busbar Protection
International Transactions on Electrical Energy Systems, Volume 2024, Issue 1, 2024.In this paper, a novel time‐domain method based on the orientation analysis of the superimposed current component Lissajous curves is presented for busbar protection. The conducted study has showed that the orientations of the superimposed current component Lissajous curves are different under internal and external fault conditions. These curves during
