DEFINITION

Classification: 315/262

(under subclass 261) Systems provided with (1) a transformer connected between the source of supply and the discharge device for supplying electric current or potential to the auxiliary electrode circuit, or (2) a transformer connected between the source of supply and the discharge device for supplying electric current or potential to the principal electrodes of the discharge device, the transformer being provided with an auxiliary winding which supplies current or potential to the auxiliary electrode circuit.
