The question is: Does the EEC bring something. If it does, what does it bring.
Can i measure or see it?
It appear to me that what it bring from the electronic point of view is a current in the high voltage line (referenced to ground) ... this current can be measured and compared with a test current of the neutralization of the gas
for example if we hold the cell at 40kv dc using one transformer we add a ammeter to this transformer connection to ground
on the gas output we add a metal tube to allow the gas pass thru it and discharge its charge on it ... if we ground this tube and add other ammeter there is possible to evaluate if there is ionized gas output and its polarity
the greater is the gas production the greater should be the current as it will be bringing charge with it as its bubbles breaks water surface tension
this is the first step to get on the eec
the next step would be to improove this ionization current but first we need to get any current to start with to know that we are on the right way
is important to have the amp metters that read rms values not peak otherwise wont be a good reading
also it would be great to connect to the oscilloscope and compare the waveforms since the gas ionization output theoretically will look more like dc while the trasnformer will have a pulsing caracteristics
than is possible to add a resistor on the gas side and see what voltage is possible to develop in it with such a discharge
for example we add a resistor of 10kohm if the current was 1ma it should result in 10v on the resistor
at a certain higher resistor value it wont be able to discharge the gas fully or even partially
the only way i see possible to determine the gas quality improvement would be a setup where the gas can be directed to a torch and to heat some water cup over it while measuring the temperature rise of the water relative to time it will be possible to determine weather the ionization is helping or not improve to some extent the gas quality
