25 HZ är fel - USA (Elektrifiering/elektrisk drift)

De banor i USA som lyckades bra med 25 Hz elektrifiering exempelvis Norfolk & Western Ry använde fasomformarlok. Alltså en enfas till trefasomformare, samt polomkopplingsbara asynkronmotorer.


Nu är jag ingen expert på elteknik och man kan inte lita på allt som står på Wikipedia men stämmer det överens med Wikipedias beskrivning av de mycket lyckade GG1 loken?


Nej, den artikeln beskriver ett transformatorbaserat pådrag, antagligen för enfas seriemotorer.

Ja det var seriemotorer.
