Well, i had a drsstc coil with about 500turns(7in tall, 4in diam) on it
with a 4 turn primary making that
1:125 ratio...My coil would do 2 feet EASILY...How do you explain that?If
it were so as you say, 220volts times125 would be 27,500volts...Thats
assanine if this is what your implying?
Id be careful with your choice of words as you came off as quite insulting!
There is a strong correlation between Vs/Vp and Ls/Lp, and likewise between
Ns/Np and Ls/Lp for ANY GIVEN TYPE OF COIL. There is not, however, a direct
mathematical proportion of the type Vs/Vp = Ns/Np as there is in ideal
power transformers. The 1500-turn rule of thumb is a good general
compromise between losses due to excessively tall, high resistance
secondary coils, and losses due to excessively small primary inductances.
The fact that the optimization curve seems to have a fairly broad flat peak
keeps the faithful faithful and the skeptics skeptical.
Based on reading prior communications over several years, I would have to
say that the insulting tone you detected from our colleague on this issue
was not an accidental occurrence.
