On the Spatial Resolution of Fault Location Techniques Based on Full Fault Transients [PDF]
, 2019 International audienceThis paper discusses the mechanisms enabling spatial resolution in fault location methods based on full transient signals, as opposed to those only using their early-time portion. This idea is found in recent travelling-wave methods

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
