P06-8463 Abstract of Disclosure A automatic voltage regulating transformer is pro- vided which incorporates a potential transformer electrically disposed across its series windings, and a set of sensing windings disposed across its shunt windings to provide a voltage sensing network which is responsive to the flow of current both into and out of the transformer. The output of the potential transformer is connected in series with the sensing windings to provide a control voltage which is repre- sentative of the voltage across the shunt windings and series windings taken together. In the case of a normal voltage regulating transformer, this control voltage is proportional to the voltage across the output terminals. In the case of an inverted regulating transformer, the output voltage of the voltage sensing network is proportional to the voltage across the input terminals. In each case the same control voltage can be used to automatically operate the transformer whether or not current is flowing into or out of the input terminals of the transformer. In one embodiment the tertiary winding that is used to provide voltage to operate the tap changing mechanism of the transformer is also used to provide a voltage proportional to the voltage across the shunt windings.
