The regulation, at least in Europe, is done at 150/15 kV substations and at
the HV side of the transformers, thus at 150 kV. Typical current for 2 x 25
MVA transformers is 150 A, 150 kV and of course secondary at 15 kV, 1500 A.
The regulation is done automatically with tap changers, live. The local
transformers at your neighborhood are fixed tap, 15 kV (they intend to
change everything to 20 kV).


So they have developed 100% efficient transformers?
