ABSTRACT:
Electric power dissipation in a mass of molten glass is increased in a controlled manner where two or more power sources are each connected to at least two electrodes in the molten glass, by cross connecting the sources through a controller so that electrodes connected to each source and at proper potentials during a portion of each power signal period are connected together. The interconnection enables a substantial increase in voltage applied to localized regions of the molten glass without requiring higher voltage sources. Adjustment of the controller as the conductivity of the glass increases avoids runaway conditions. Interconnection of single and three phase power sources is disclosed.
