Abstract
A voltage regulator (10) for regulating a power distribution system voltage during forward or reverse power flow. The voltage regulator (10) accommodates multiple configurations of a tertiary winding (30) and a potential transformer (36) connected across source-side bushings (S/SL) or load-side bushings (L/SL). The invention simulates operation of a potential transformer (36), and the output voltage therefrom, connected across the source-side (S/SL) or load-side bushings (L/SL). The invention also produces a corrected voltage compensating a non-standard turns ratio of the tertiary winding (30). The regulator (10) controls a tap changer (18) to regulate the system voltage according to a digital value representing the voltage across the source-side (S/SL) or load-side bushings (L/SL), comprising a measured voltage, the corrected voltage or the simulated voltage. The digital value is converted to an analog voltage and supplied to external terminals (102) for measuring by a service technician using a voltmeter (104).
