Are transformers used for Neons different than transformers used for other electronics?
Yes, luminous tubing transformers, sometimes referred to as high leakage reactance transformers, differ from power transformers. Power transformers are designed to have good voltage regulation over varying load conditions where the output voltage varies only slightly from no load to full load conditions. Luminous tube transformers have deliberately poor output regulation due to magnetic shunts designed into the construction of the transformers. Poor regulation is necessary to limit the current for proper operation of luminous tubing. The reason for this is because luminous tubing requires a high voltage to start the flow of current, but the transformer must maintain output load current within a narrow range.
