ABSTRACT:
An electronic device for compensating voltage fluctuations in an electrical power distribution circuit controls operation of a transformer of the type having a TCUL voltage regulator by automatically calculating the voltage bandwidth of the transformer based upon a stored value for peak current in the distribution circuit. The peak current value is automatically updated when the actual current in the circuit exceeds the stored peak current value for a predetermined sustained period of time indicating a change in overall loading patterns in the circuit but, regardless of increases in actual current in the distribution circuit, the apparatus prevents the output voltage from exceeding a preset absolute maximum.
