The 3 indicates RYB and .5 Neutral. In normal conditions,
power supplied is balanced. So, no neutral current flows.
But in case of small unbalanced condtions, low amount of
neutral current has been found and hence to provide the
path for it, neutral wire is provided with half of the
cross section that of phase.

when generator short circuit condition, the current how dissipates. or at short circuit voltage not available then current how can flow?

in general it is observed in power stations, the tertiary winding is used in higher rating Y-Y auto transformer but not in Y-Y power transformer. is the tertiary winding is compulsory then why it is not using in power transformer
