[QUOTE="Sidewinder, post: 349680, member: 9512"] Deke, I don't think resistance will tell us, each of the windings are equal resistance. Letting the ends be as you have labelled them a, b, & c. a to b will be two windings, b to c will be two windings, c to a will be two windings, if star. a to b will be one winding, b to c will be one winding, and c to a will be one winding, if delta. Trouble is we don't know what the resistance of one winding is, so we also don't know what the resistance of two windings is either. Not blindingly obvious really. Hence why I posted. I'll have a look at what technician has posted later if I get time. I think we need to stick known currents & voltages in and see what we get as an initial guess. [/QUOTE]
