Original poster: "harvey norris by way of Terry Fritz <twftesla-at-uswest-dot-net>" <harvich-at-yahoo-dot-com> I am getting a kick out of these polarity posts and the 3 phase AC thread which I may post to later, after I am more sure by tests of my remarkable conclusions. This has to do with the fact that in a source emf WYE to loads as DELTA series resonances, all three phases must be resonant for any of them to be resonant, and if two phases are not completely resonant, it will prevent the third one from doing so. Talk about tricky tuning! But to convey the idea of polarity here the 3 phase example makes it very easy. A series resonance is a quantity of L and C values satisfying resonant Thompson formula that can be wired in series and connected on each end to its polarity inputs. We have two connections and two ways to hook it up. Therefore we also specify that all three resonances are ordered or hooked up the same way as *LC*LC*LC for all 3 of them to be 120 degrees out of phase. It is simple to the understand then if one of these LC combinations were reversed, it would then be (120-180)=60 degrees phase separation instead of 120. Now the above argument is easily visualized as an inverse resonance example. The question then becomes how do we visualize the same thing for 3 parallel resonances? Or for that manner how do we even do it for a single tank circuit! That is puzzling because there is no difference in simply plugging in the circuit backwards, it is schematically the same thing. That is where the conception of loops sharing a common path make this explainable. In the unused 90 degree phase generation system two 1 amp phase consumptions instead of using two return wires of 1 amp each can be combined into one wire carrrying the phase summation of the square root of 2 amps=1.41 Amps. This represents the vector addition of two 90 degree phase currents,or the hypotenuse of a unit rt triangle That return current represents a path shared by two current loops, and the resultant reduction in return currents is made by that partial cancellation of phase currents. In three phase,the return wire path for a 4 wire wye delivery can exist in complete cancellation, provided equal amperage consumptions exist on the three phases. The entirety of the return currents is made as a preferred pathway on the adjacent phases. The option of 180 phased inputs is a condition for making the seemingly impossible 180 phased tank circuit. This takes the form of a center tapped transformer secondary. Each of the bifilar secondary winding directions are reversed on the primary core, so that the emfs are of opposite or 180 phased polarities, where the provision is made that these two current loops also have a grounded shared current path. Again if the amperages on each side are equal, no current will exists on the center tap return path, because of 180 phased currents summing to zero. The return current is made on the opposite phase instead of the center pathway of phase cancellation. This of course is the grounded path. Now let us apply resonance to the below posting; --- Tesla list <tesla-at-pupman-dot-com> wrote: > Original poster: "Eric Davidson by way of Terry > Fritz <twftesla-at-uswest-dot-net>" <edavidson-at-icva.gov> > > Hi All, > > To make the idea of polarity a bit simpler, lets > disconnect the grounded > center tap on the secondary of the distribution > transformer.

Applied to resonance we can also resonate two coils 180 out of phase from each opposite 120 volt inputs on each side of a center tapped secondary and obtain a voltage rise by the q of the coil that can be measured from the middle or midpoint of the LC circuit to the outside where the ends of the circuit are connected. Since each of these voltage rises are on opposite directions of polarity, there will exist 2 q of a voltage rise between the midpoints of the oppositely phased resonances. This is the same result that inputing the coils at twice the voltage would give. We still only > have one phase. Yes but it depends how we hook up the resonant LC quantities that always determines two options. By containing two paralleled opposite LC quantites from the same input we can create two opposite voltage rises, however simply placing the coils themselves in series and resonating them instead of 180 phased parallel example will deliver the same voltage rise. The 180 phased example is the analogy of resonance from the concept of a simple transformer to that of a center tapped transformer secondary with shared current loops in cancellation. There is an important distinction however, in that all the previous examples of pathways with shared current loops showed that shared pathway producing a partial or full cancellation of the currents that would exist on that pathway. There is also the possibility of doing the reverse application. This is actually shown in balanced,(no return 4th wire current)Delta 3 phase delivery. In that situation Each of the 3 supply lines are supplying two phases, where at a particular point in time, it is not only supplying the one unit amp for one phase, but also the return .7 amp for its adjacent phase. Thus for three phases of one amp currents, the "shared loop" pathways of the supply lines at 1.7 amps are greater than the individually phased currents. Now to return to the paradox of constructing a 180 phased tank circuit, this could be done by using a center tapped transformer, with the traditional shared current loop in cancellation. But here is why I brought up the three phase issue for simplicity. We can easily imagine three ordered delta series resonances in delta, and because of the three phase inputs we know each of the circuits are 120 degrees out of phase. If we now place a wye short current path between all midpoint q rises as shown at http://www.escribe-dot-com/science/freenrg/m9505.html we will have converted the three series resonances into three tank circuits, with the provision that each of the tanks with have portions of shared current paths of adjacently phased tank circuits. It is on these shared current paths that we see that the 3 phase tank circuits internal amperages are 1.7 the amount of amperage on the shared pathways, than on the outside individual phase pathways. The new configuration has actually turned the tanks to a shared path of connections in WYE. A wye circuit is specified as using a 4th return wire for the case when unbalanced currents among phases occurs. If this is not available then the amount any phase can conduct is also tied to the amount of conduction made on those adjacent phases as a return wire pathway. In this way it was found that the nonresonance of two phases can limit the possible amount of resonance on another phase.The same situation applies in reverse for tuning the outside ordered DSR's, because of the internal wye stator field connections. So making a complete AC modification of a car alternator should ALSO always consist of making a fourth return wire from the stator connection. I have not tried this yet, but undoubtably if it were there for the return currents it would uncomplicate the 3 phase tuning situation. So in summo it should also be seen that when the same situation is made on 180 phased series resonances: where a short wire is made between their midpoint resonant rises of voltage, this circumvents and changes the circuit into a figure 8 tank circuit, where that pathway being shared by those L and C reactive circuits is a shared pathway used from opposite directions of travel, leading to unity instead of cancellation as a shared current loop pathway. Since this is unity of each reactive current, twice that current then exists along that shared loop pathway. Three phase resonant midpoint voltage rises with appropriate LC quantities used at 188 hz are shown at http://msnhomepages.talkcity-dot-com/LaGrangeLn/teslafy/trinity.html and schematics on the following linked page. Also the concept of using these resonant voltage rises as a resonant transformer; http://www.pupman-dot-com/listarchives/2001/January/msg01175.html Sincerely HDN ===== Binary Resonant System http://members3.boardhost-dot-com/teslafy/ __________________________________________________ Do You Yahoo!?
