I'm working with a neon sign transformer and want an indicator (preferably a light) on the high/output side to give me a visual cue when there is current coming out of the transformer. I'm not 100% sure how to do this, and given the output voltage, I don't want to make something by trial and error. I've been having a hard time finding resources or parts and I suspect I'm googling the question properly.
I've attached a very rough schematic of what I'm trying to do. Transformer Input is 120VAC/0.9A, grounded on the supply side and coming from standard 120V wall power. Transformer Output is 10kV/30mA I want a lightbulb indicator on the 10kV side.
This link is the closest I've been able to find, but it's not quite what I need.
Do I need to get a transformer to get the output current back down to 120V for a bulb? Or is there some indicator device that can sit on the 10kV line?
What should I be looking for and asking for as I hunt for this device or design the circuit?
Thanks in advance. D
