Hi,
Can someone comment on if a star-star auto-transformer which has a direct earth connection, and which has a delta tertiary where the tertiary is earthed via a reactor to ground, if there is a line to ground fault further down the network will both the auto-transformer neutral and the tertiary neutral carry fault current?
Thanks
