Great post Bjarney!.
Us guys over here had the 2 transformers up on a set of poles + a platform for the Xformers.
Purely 22kV Line stabilisation, but as far as I know they were configured in a Scott Connection, where 2 HV windings feed 3 HV windings of the same voltage.
Can you shed some light on this Bjarney?.
Not long before I left Temuka, to come to Ashburton, they were Undergrounding all the services and the Scott Connection was lost, in that part of the world.
Changed for plain vanilla Delta-Star Xformers.
Damn, take all the fun out of life why don't they!.
