WebApr 27, 2024 · The recloser–fuse coordination study has also been carried out in the presence of FCL and DGs in the IEEE-33 bus test system. The fault current calculations have been performed in the presence of a single DG with single FCL and multiple DGs with multiple FCLs. It is to be noted that the FCLs have been placed in series with the DGs.
