   Far as I know all neon sign transformers in the US have a ground   
   referenced secondary. For instance, a common 15kV transformer has a   
   secondary center-tap connected to the case. Likely common practice   
   elsewhere.   
      
   Neon sign transformers are basically constant current sources. The   
   voltage from a loaded transformer might be 80% of the rated voltage.
