In the 3 phase system the delivery line, which is one of three can carry 1.732 A delivery current which then splits into two individually phased one amp currents. These phase delivery currents are themselves 120 degrees out of phase with each other, and obviously also out of phase with the delivery line itself. Because of this delta load phase splitting, Kirchoffs laws of junction currents is seemingly violated where what goes out has become greater then what went in at the node... This appaent contradiction does not consider the TIMING of each AC signal. The complication is resolved when we consider the total picture using all three phases. Suppose we had three different electrical co.s each selling a single phase of electricity, but that each one was operating 120 degrees out of phase with the other. In this case of single phase electricity sold by each Co. the delivery line current and the phase current of the load are one and the same thing. One AMP delivery yeilds One AMP phase current. But in actuality it cost the electric CO the line losses of TWO delivery lines, since there is an enter and exit line for the single phase of electricity. Thus we have six lines of sending and recieving currents for three loads. Now suppose the electric Co.s all merged so that they shared each others delivery lines. The sending line current of one Co.s current will be paired with the recieving line of its neighboring co. on each side. The vector combination(which is actually a vector subraction and not a vector addition, since these are sending and recieving currents from each phase) of both the sending and recieving currents on both lines shows that when the two one amp curents were combined in parallel lines, the two amps was reduced to 1.7. And perhaps more importantly the Co.s in unison merely made two lines in to one, reffered to as stator line currents on the example of a 3 phase alternator. This also means that now instead we have three loads having only three delivery lines, instead of six. Now if we carried forth this same argument for quadrature phasing, the shared 1 amp lines would enable 2 amps of phase currents to be delivered to the quature corner at an even lower l.4 Amps delivery line current. The question then becomes does adding more phases automatically guarantee further gains in efficiency? No it does not... As proof of this let us investigate a hypothetical 5 phase system. In the first case the three phase system delivered three one amp currents at a cost of(the square root of three)= 1.7A on the delivery lines. In the second case the quadrature system delivered four one amp phase currents at a cost of (the sq root of two)= 1.4 A on the four delivery lines. In the hypothetical five phase system we have the sq rt of 5 = Five 2.23 Amp delivery line currents to enable five individual phased one amp currents. So we here can see the superiority of the quadrature system in showing that no other polyphasing scheme can superceed its % of delivery line vs load line currents. This is also for a simple rule of vector addition vs vector subtraction. Only a 90 degree angle between equal vectors gives equal magnitude results for both addition or subtraction.
