EDIT; This is from a combination of two posts I made earlier today @ O.U.com....
my English is bad but I'll try to explain that you have no chance to tune Akula's device if you don't know how it works. I hope Wesley will translate latest Akula's conversation on skype. but in short, Akula's devices is working on core resonance. It's different cores - different resonances. for example one Akula's core have 3,5 Ghz resonance. transistors switching time need to be shorter than this frequency. the high and low frequency generators need to be harmonics oscillators on cores resonance frequency.
from start you need to find core resonance that you have.
the transistors switches need to be switch on-off in one time
and there is more what to be explained but I hope somebody do better than me
Hello All:
I believe this to be relevant concerning ferroresonance and dimensional resonance:
and in relation to AC power systems:
"Ferro-resonance can generate overvoltages of upto 12 times line to ground source voltage upon opening a single phase device or poorly synchronised 3 phase device. Voilent failure can occur exposing personnel to the high voltage failure and accompanying conditions. Ferro-resonance conditions can result in damage to lightning arresters, switching devices, buried cable, transformers and associated equipment.
Ferro-resonance can be initiated when all of the following elements are present and the switching means at the dip point or takes off when a single phase device or an unsynchronised 3 phase device that does not operate all phases within 1/2 cycle.
1.System grounded at the source, but with no ground at the transformer bank
2. Shielded cable length or overhead conductor length sufficient to create the capacitance necessary
3. Transformer size that permits saturation of the iron core at the operating voltage
4. Transformer unloaded or lightly loaded.
Prevention or control of ferro-resonance can be by:
1. Using wye-wye transformer withboth neutrals grounded and tied to systems neutral
2. Using only phase-to-neutral (not phase-to-phase) transformers connections for single pahse transformers.
3. Limiting length of underground cable
4. For poorly synchronised switching devices, extra resistive load of 2% of the transformer capacity on underground cable. "

Food for thought, and it does correlate with the
Russian stories of the cores self-destructing after a short runtime:take care, peace
