The 750/760 detects a VT fuse failure when there are significant levels of negative sequence voltage without
correspondingly significant levels of negative sequence current measured at the output CTs. Also, if there is
not a significant amount of positive sequence voltage when there is positive sequence current then it could
indicate that all the VT fuses have been pulled or the VTs have been racked out. The setpoints are as follows.
