Zig Zag transformer offers a verh high impedance to positive sequence currents and negative sequence currents whereas the impedance it offers to zero sequence currents is less. As earth fault currents are zero sequence, this transformer would offer a low-impednace path for all earth fault currents.

As regards the write-up on transformer vector group, I have, in fact, written a detailed article on the subject, but it is too long to post here. However, if you can inform me your mail ID I will send you the same.
