The cross-bonding system uses major and minor sections as you've described, with solid earthing boxes at the major section boundaries. The problem was across all major sections - every single set of links had to be reversed.
We checked the phasing of the sheath, it was marked correctly at all...
The client's since agreed the links are the wrong way around, but why does it actually matter?
The purpose of cross-bonding is to ensure sheath phase transposition (i.e. the 'contiguous' sheath spends an equal distance adjacent to red, blue and yellow phases) so why does the direction of...
Hi,
We are performing a cross-bonding verification on a 220KV cable circuit with 11 joint bays.
The links and SVLs at all locations (termination link box and joint link boxes) have been placed in the normal service position.
At the far end of the cable, we have connected the three cable...
