Re: The Two Legged Wye:
Jim, what I said in effect was that apparent power is simply VxI with no PF. You now are talking of derating the open delta to 57.7% of its full rating. I would not deny that, but that has no bearing on my first statement.
As for the O.F.F., it is no trick. It is the simplest, most direct computation you could make to find the allowable current in the two legged wye. It may not be widely used, but you yourself have tacitly admitted that it works, so how can you say it is a trick?
Now, do you also contend that power is a vector quantity?
