      As previously noted, three options of placing a neon across the
      secondary power transfer exist. The neon can be plced across either
      L2 or C2 of the secondary in which case a diversion of resonant
      current exists, or one can ground the neon from the L2C2 midpoint
      voltage rise, which is the case beying employed here for testings of
      between 70-~100 watts with the primary configured as the series
      resonant L1C1 quantity noted as DSR1. The third option would be to
      place the neon between the midpoints of primary L1C1 and L2C2 for an
      autotransformer application.

      There is a great problem in these testings with the meters involved
      changing what we are trying to test. A neon firing at its lower
      parametric emf inputs of lower voltages will have its discharge cut
      in half the moment a voltage meter is placed across its voltage.
      Addtionally the scale of amperage reading being changed from the
      higher 400 ma-20A, to the lower 4-400 ma range will act to add
      impedance to the amperage conduction being observed. This may have
      inadvertantly omited from postings as I cant find the message URL in
      archives so I will repost this now from Fri 10 May 2002;

      Deviations on 3 phase made with 480 hz DSR1 Amperage meter To:

      By simply changing the scale reading of the amperage
      meter recording the voltage and amperages to be
      delivered to a DSR1 opposition, this changes the
      effect shown in small scale. This is to indicate that
      small and large scale differences exist, and the
      monitor for small scale can change the observation
      made on larger scale.

      These differences of extra "impedance" added by the
      DSR1 amperage meter shows dramatic changes on how the
      meter scale amperage reading itself changes the total
      3 phase interaction!
      DSR1 amps on high scale
      Here 1.618 parametric stator volts is enabling .29
      Amps on DSR1 phase. That amperage meter has a better
      scale to make the reading more accurate, as this scale
      is for 400 ma to 15 A. However in this larger scale
      amperage reading the V(int) reads 8.34 volts for the
      1.6 stator and the MIDPT volts reads 28.35 enabling
      3.704 ma acraoss ~1 nf capacity with neon leakage
      DSR1 amps on low scale
      This shows the changes brought on by DSR2 side
      resonances by the mere change of DSR1 amp selection
      range to read more accurate! The former reading of .29
      A is now 288.9 ma, in close agreement to former. But
      now DSR1 voltage rise is reduced to 7.14 volts, and
      DSR2 has been reduced in operation with 20.22 volts
      enabling a ~10% reduction of interphasing conduction
      to ~ 3.3 ma from the former 3.7 ma. The DSR2
      metering doesnt lie, but the DSR1's dont either, but
      one changes the other! Therefore we must conclude
      extra impedance at 480 hz is somehow added by the
      measuring instrument itself when placed on the lower
      scale amperage reading.

      That 480 hz effs with meter scales to a great degree,
      and in this example the variances brought forward for
      prosecution in three phase alternator processes are
      made self evident to a great degree. HDN

      Now here in this situation the same thing occurs by adding a amperage
      meter into the circuit to make a comparison between the actual neon
      current, already having a voltage and amperage measurement placed
      across it as the amount of current being diverted from the resonance.
      Undoubtably there is much more reactive transfer of energy in the
      resonance itself then is recorded across the bulb. But when we go to
      measure that quantity, that measurement in turn may change the
      operation of the neon currents themselves. It is also to be noted
      that I had mentioned a mistake, in that the voltage meter across L2C2
      itself remains minimal and reads in millivolts, not volts. The
      secondary L2C2 at higher primary wattage does start recording in
      volts at this 75-100 watt level as shown in
      L2C2 Secondary Neon Grounding Measurement
      Here a 25.7 volt stator is enabling 3.93 Amps on primary, ~100 watt
      input, with resonant voltage rise to 117.7 volts to enable that
      current with the L1 voltage meter across the white 14 gauge coil of
      one ohm. Mipt volt meter across L2C2 in series records 7.69 volts.
      The high induction coil L1 sits on is the L2 coil with its C2 plate
      capacity in the foreground. A neon attached to L2C2 midpoint and
      ground displays very low voltage of 120.6 volts enabling a current of
      3.2 ma. Having noted the midpt voltage this meter can now be changed
      to read the actual amperage between L2 and C2, which should show the
      higher amount of amperage circulation between those secondary
      elements, an amount surpassing that shown by the neon conduction to

      Comparison of Grounded Neon and Secondary L2C2 Currents

      Here a 22.77 volt stator enables a 3.48 Amp primary consumption, with
      104.5 volts resonant rise on L1. L2C2 circulation current reads 13.2
      ma,(midpt Amps) but as a consequence of this amperage measurement the
      voltage across the neon has shown its customary level of 442 volts
      enabling 2.7 ma on the neon ground path itself. The actual internal
      voltage at L2C2 midpoint would be about 4170 volts, and near this
      range the plate capacitor will start emmiting sound. The higher
      voltage across the neon appears to be a consequence of making an
      amperage measurement on L2C2.
