you have to agree :-D
the voltage that present on the primary in all my charts is equal to
zero, coz the maximum potential difference between pri & sec is
achieved only at the full energy transgfer moment - at this time Vpri=0.
but there`s no difference if the 100kv is on the primary or on the
secondary, coz field strength depends from the voltage beetween the
conductors and their ROCs, so it is the primary that has serious
problems - not the secondary.

electrical stress is not in the LDPE, but in surrounding air, coz "e"
of the LDPE is greater than "e" of the air, so field strength in the
air is greater than in LDPE.

unfortunatelly the proggy has no such things as
"slightly-electrically-conductive" iiuc :-)

yep, i think that all of us know that to a greater or lesser extent %-)

thanx, today it`s really warmer here - not only in centigrade ;-)
