Serious problem: 3 to 1 phase transformer? hepl me

This is so called scott transformer. pls search this cr4 or google for detail.

3 to 2 or 1

Im afraid I cannt find it in my computer now. I forget where I put it.

I try and show you if I find it.

I sent the photo to your mailbox. pls check.

hi,

i saw something same used to supply basler PRP210 reverse power relay and its called three phase to single phase matching transformer. thats all what i know about it but i cant tell you how does it work?

i was going to ask this question!!!

thanks

This sounds like a "ZIG ZAG" connection where two secondary phases are connected reverse polarity with the third phase. In a three phase delta network the instantaneous sum of the voltages is zero (Otherwise the network would be a big short circuit).

Therefore the instantaneous voltage of any two phases equals the voltage of the other phase, and the result will appear to be a single phase. This circuit is used often to use three phase generators (Alternators for you purists) as single phase power source.

Consider the "ZIG ZAG" of two phase secondaries as 2/3 of a Wye network connected in series with the third phase. The connection between the "ZIG ZAG" of two phases and the third phase would show the same voltages as a single phase center tapped transformer.

Any Help[???? CEKM
