Parallel TX Tails - Neutral Arrangement

MW (aka Inrush - for those who remember me!) over 6 years ago

So this is the new look forum... Impressive!

I have a question regarding AWA transformer tails. I'm looking at a situation where I need three parallel cables per phase.

My question is related to the neutral conductor arrangement. The neutrals need to be installed between the inter-group trefoils in order to maintain equal current sharing. Therefore, I can either have two neutral conductors of slightly larger CSA to give approx. the same CSA as the overall parallel phase conductors. Or, alternatively, three neutrals of the same CSA as the phase conductors split (oddly) between the two groups.

What convention is normally adopted in this situation?

Many thanks in advance.

Thanks all (especially OMS and Mike). As the quad layout (for three parallel phase conductors) is not mentioned in GN6 any chance you can point me in the direction of any reference/technical information covering this arrangement?

Thanks,
