RE: [TCML] single ear transformer

[Quarkster <quarkster@xxxxxxx>]

Gates -
 
A few more details on this transformer, and your Tesla coil, might allow the TCML to better understand your setup and make appropriate suggestions.
 
1. Are you trying to retrofit this transformer to an existing, operational Tesla coil, or is this a Tesla coil that is just being assembled and is not yet running?
 
2. Can you provide additional details on this transformer, like its output current or KVA rating,  physical size/shape, and original application, if known?
 
3. With a 30KV RMS output (assuming that you apply the full 120VAC input 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?

Herr Zapp

The output is rated at 30KV the case ground is just a regular house green
ground for the case

only has one output, which grounds to the case, then you tie the case to one
side of the spark gap/capacitor, and the output terminal to the other side.
