Abstract
An ANSI Type A voltage regulator that eliminates the need for a potential transformer is disclosed. A control unit finds an output voltage by constantly monitoring the input voltage across the utility windings and the stored tap position. The value of the output voltage is further fine tuned by taking into account the effect of the impedance of the voltage regulator itself on the output voltage. The impedance is calculated using the instantaneous current through the regulator, the maximum rated current of the voltage regulator, the instantaneous voltage through the voltage regulator, the instantaneous Power Factor, and the tap position of the voltage regulator.
