i bought a transformer to bump from 240v to 415v so I can run my vfd and supply my work shop with 3 phase power at 415v!
from what I can determin it has three primary windings origonally conected in star the imput was 3phase 415v simpl enough although there was a newtral conected to the star point and from the colour of the wires it looks as if there was a lot of power going through it?
but the seckondary windings are an open delta arangment
the center primary winding has no seckondary winding on it .
can some one tell me weather it will work in reverse enabling 240 single ph in 415v single phase out and what is the purpose of the center primary winding is?
