Hi Boris,
  No.. I'm pretty sure that was peak.. and those voltages
are always quoted line-to-line.. so:

768kV(peak)/SQRT(2) = 543kV RMS 

Then to go from line-to-line to line-to-ground:

543kV/SQRT(3) = 313kV to ground

Line-to-ground is always lower than line-to-line.. so that
sounds about right.. ;)
