Iberdrola Renewables,
(formerly known as PPM Energy) has chosen Prolec GE to supply high-efficiency
transformers using amorphous metal for four of its wind farms.
Prolec GE's
high-efficiency transformers are based on amorphous metal cores, which
significantly lower no-load losses by 60 to 70 per cent as compared with
high-efficiency silicon steels. Prolec GE's high-efficiency amorphous core
transformers are being installed at four of Iberdrola's wind farms including:
MinnDakota, located on the border of Minnesota and South Dakota; Casselman,
located near Pittsburgh, Penn.; Klondike III, located near Wasco, Ore.; and Elm
Creek, located near Trimont in southern Minnesota.
