Must have missed that science class in middle school. Qsep does not understand why Voltage is decaying or “leaking”. This indicates the field generated is finding an alternate path through the the treatment vessel even though they had the chamber retrofitted and insulated and done this dance for years! They don’t want to call it a “short circuit” but it’s not a good thing anyway you look at it. In engineering it’s good advice to be able to account for the bulk of the generated electrons!
