The Natural Philosopher explained :

11KV round here. Underground. Watched em put in in

I can find no mention of 3.3KV grid ANYWHERE at all.

It's used primarily for motors and as an intermediate voltage in power
stations. Never for any distance transmission.

i.e. NOT as part of the grid.

However the subject under discussion moved away from what everyone
would understand to be the grid, to local distribution. It was on the
subject of local distribution that I responded.
