DOI: 10.1109/tie.2023.3337500
Abstract: A single-line-to-ground (SLG) fault occurs at the ungrounded side of a transformer (e.g., wye-grounded-delta, wye-grounded-wye, or wye-grounded-wye-grounded through a large impedance transformer) in a grid-forming inverter will cause severe physical overvoltage and inverter output overcurrent… read more here.

DOI: 10.1109/tpwrd.2018.2873017
Abstract: In the event of a single line to ground (SLG) fault in a non-effectively grounded distribution network, the faulted current is weak (only a few amperes or less) and the existing devices cannot accurately judge… read more here.
