# Nst transformer?

How do I find out how much current my transformer can drive? How do I compare the drive of my transformer, and what's the purpose?

power is not my first concern.butBut our author was asking about an NST ( Neon Sign Transformer )

and today that could be a resonant instant start transformer with air-gap

current limiting final output ( hard to use on anything else then mercury vapor )

A

So, OC volts = 1000V,

SC amps =0.03

resistance = 1000/0.03 = 33KOhm.

Load = 33kOhm, output power =

500^{2}33k

=7.5W. Put your own,. accurate, numbers in
