Again I hear ya.Well, if it is convention to call that 'one phase' then that's the convention! Still makes no sense to me to call anything other than 180 deg phasing 'two phase', but if that's what folks do, then that's what folks do!
So what do I have if I connect the three secondary windings of a three phase transformer or transformer array in a delta configuration so as to deliver three phase two hundred forty volt power? That is three phase is it not?I don't see what you are saying.
A 'neutral' is a line with [nominally] constant charge on it (hopefully 'net neutral charge', if earthed).
A 'hot' AC line is one with periodic time-varying charge on it.
Two phases are two lines with periodic time-varying charge on them, but of different phase angles.
A two phase system is one with two lines with periodic time-varying charge on them at 180 degree apart. You get this from one phase feeding into a transformer with a grounded center-tap secondary. The two outputs will be at 180 deg out of phase = two phase.
No, you cannot tap any old number of phases off a simple transformer. If you feed one phase in, you get one phase out of one winding, or two phases out of two windings which might be 180 translated.
I feel the same too. Using the same term for what you call "Split Phase" and a Three (or any multi-) Phase system is not helpful. Whilst it is possible to represent two anti-phase signals on an Argand Diagram, just as you can represent a multi-phase set, is there any point? The situation is one-dimensional and does not call for a 2D representation. It's such a special case that it should be treated and discussed differently.ted.
I have been wrong before and I will be wrong again but I just cannot buy a split phase being two phases.
