Using neons for limiting?

Is it possible to use a neon with its secondaries shorted for current
limiting? Or perhaps an induction motor in series with the transformer.
I am not talking about using these long periods of time but I would like
to use them so I can test my potential transformer. The potential
transformer I have will draw ~34A at its rating. I only have a 20A
breaker to run it on. So I am wanting to limit it to at least 15A maybe
20A max. I have a neon that draws about 13A, but I don't want to destroy
my neon either (12kv-at-90ma).
