Subject: which disease?
Dear All, I need some help.
I wound a coil (diam. 4.33", height 33.66") with .35mm wire (AWG 28??)
and a total secundary resistance of approx. 155 ohm. I thought that
these 790 meters from 2290 turns would give me resonance at 94,8 kHz.
Why not???
Everybody talks about 3:1 ratio but that means with 10" diam
->30"height, doesn't it. How do I get 1000 turns in so little height.
Can I take a form with more height??
I now get breakouts (>20") at half of the form, distroying my turns. I
am using a cap wound from 2.5mm thick red plastic (don't know the
material) 2 plates from about 20 cm widht and 7 meters long. Primary is
7.5 turns of .5" copper tube, gap=single .5", toroids vary. Best
sparklength I get (don't understand!!!) with a very small toroid! Supply
is a 10 kv 10kva plate transformer and a variac.
is it wise to build a new coil with 8"diam and what height and number of
turns should it have??? What wirediam??? I am thinking of using wire
used in mainssupply (2.5 mm2). at least is low resistance. What am I
doing wrong?
Please advice and thanks,
