I have a few piccies from an 2 phase to 1 phase SWER transformer in the Mangamuka's.
I ask Trumpy to put the photo's on , but SWER is well alive in New Zealand in 2006. [Linked Image]

Next month I'm in Coromandel for holiday and see if SWER still in use overthere too.

The product of rotation, excitation and flux produces electricty.
