RE: [TCML] single ear transformer
Sound like a cool beastie. What's the KVA rating?

This transformer was used to test rubber gloves for hydro workers It looks
like special order. Measures 14"long by 15 1/2" high by 13 1/2" wide its
square shaped 120 Vac input 60Hz and one bushing for 30 KV output.
I will build a whole new coil to accommodate its power.
Anyone with plans for such a beast????
I tested it with my HV meter Brought it up to 20KV no load kinda scary!!!!!
Keep in mind I don't really need to run this thing full boar
Can one post a picture of it for the list to see?

voltage), the peak secondary voltage will be over 42,000 volts. This high a
voltage will require a pretty robust tank capacitor, and special
construction techniques throughout the tank circuit to deal with corona,
surface tracking, arc-over, etc. Not many Tesla coils operate successfully
with this high a voltage in the tank circuit. What type of spark gap will be
used in this setup?
