Hmm..Seems we are digressing bit of concentration to
bare secondary behavior (without arcs).OK,I can live
with that.
One of Arc Curent Waveforms of Electrum ,as presented
on www.lod.org page,gave me for corona resistance
about 100 kohm when I calculted it.Malcolm and I
discussed this few months ago and he agreed with me as
concerns this figure.200 kohm isn't still definite
part for corona model impedance.But it is good start
anyway ."Magic" of arcs isn't explained completely
yet.

Boris
