    Current flow direction through a star point CT?

    Could anybody advise please? Which direction does current flow during an earth fault through a star point CT? The CT is around the star point earth cable.

    CT label

    I have a CT label (ring type) that has a line: VA/cl. 5/1-7.5/3 I know the 5VA burden and class 3 but what does the 1-7.5 signify? And, am I correct in thinking this is a metering CT? Thanks for all help.
