Would a DB fed from section board be considered as the origin in regard to ze or would that be at the section board.

Cheers guys. Wasn't sure as it's a factory set up feed from 11000/440 transformer to section board (fuses for dbs) then to distribution boards.

Remember; Ze is the earth fault loop impedance that is external to the installation
