Original poster: "harvey norris by way of Terry Fritz <twftesla-at-qwest-dot-net>" <harvich-at-yahoo-dot-com> I have used this two wire method of alternator input to run a secondary arc gap connecting a possible TC primary /secondary coil. Didnt find the correct tuning yet, using .6 mh and 1 nf for a 200,000 hz try. However the primary has a tight volume of spirals which needs to be expanded to be the same diameter as the secondary. But here the arc gap is easily made to function, but at increased voltage input the BPS rates seem to sound very high, and quenching problems seem to come into play. The single alternator phase input of ~ 33 volts enabling 4 amps conduction is thought to have produced ~9300 volts at the gap. Thus the alternator can feasibly drive an arc gap, but the work to incorporate this with a TC design remains to be done. More exacting equal reactance measurements showing the 1 ohm 10.8mh coil to be in resonance at 480 hz are made at http://groups.yahoo-dot-com/group/teslafy/message/385 I had initially thought there might be something strange about these mutual inductances, which others have indicated to be normal. To better clarify the confusion here a more concrete concise description can be given. Two of the phases of the alternator are delegated to produce a magnetic field assumed to be massive because of the excessive amount of turns, where magnetic field intensity is amp turns/ divided by length. However several factors, most importantly the internal capacity of the massive turn coil: prevent that amperage from developing for the impressed voltage it is given with resonant combinations, and only a possible q of 8 can be made by those methods, where the coil being used here would have a q of 160 at 480 hz, were the ideal voltage rises to become possible. Next a low ohmic coil is used for the third phase placed in resonance, where that phase also has different, but less drastic limitations on its possible amperage delivery. In this circumstance we are tuning the 10.8 mh primary to the conditions it will see when either placed in magnetic unity with the massive turn coil, or put in magnetic opposition with that coil: Where both of these coils are also placed together in space for air core mutual inductance. Thus each differing impedance can be measured and the coil assigned an new "acting inductance" for its new condition of impedance. "Now in each of these circumstances we can see that the coil acts with different impedances, thus we can give each X(L) value an acting inductance brought on by mutual inductance, and to also see how this deviates from the measured 10.8 mh value For Opposition X(L) = 20.68 ohms ~ to 6.86 mh For Unison X(L) = 34.3 ohms ~ to 11.37 mh, thus only an increase of .57 mh from 10.8 mh LCR meter measurement, but for the opposition case more than 4 mh acting inductance has been removed. This shows the degree of mutual inductance that the L2 coil makes on L1, where then the method seems to indicate that it is easier to decrease the impedance than to increase it. (There are additional reactance considerations here also with the actual timings of each field, because we are comparing reactance currents with resonant in actual timing)" Now what is further found in these 3 phase interactions timed by resonance to make 180 field interactions, the same effect occurs on the side using two alternator phases, when in fact those phases are disconnected, and thus the device is acting as an air core transformer driven by a single alternator input. The secondary normally has its currents induced 180 out of phase with the source by Lenz Law. Since we are able to miraculously produce these currents, this should also be reflected by a decrease of the primary impedance where it is noted; "Thus to compare these actions first only the 2 wire case is noted 1.79 stator volts enables 309 ma where individually X(L) reactance consumption; 1.95 volts enables 82.4 ma = 23.66 Ohms X(C) reactance consumption: 2.13 volts enables 91.2 ma = 23.35 Ohms Now for the five wire delivery we have two reactive amperage consumptions to be noted, unison and opposition, where any supposed increased impedance cancellation on DSR1 can be noted, since now we are reacting "real magnetic fields together" instead of the reaction field with its source, as occurs in 2 wire input. For the 2 wire delivery that acting X(L) at 23.66 ohms would be an acting inductance of 7.84 mh ,which is a 3 mh reduction from isolated 10.8 mh measurement." Thus to conclude for the 2 wire air core model the impedance of the primary was decreased 72.6 % by the induced currents in the secondary, but in the 3 phase delivery the impedance in the 1 ohm reactance was reduced 63.5 %. Paradoxically that reduction is not however translated into a higher amperage delivery of the primary, because this mutual induction also limits the possible conduction to half the level available in primary isolation. The primary can be removed, retuned for isolation at 10.8 mh and yet deliver more current than the mutual induction case, even after retuning.
