Abstract
An apparatus and method for controlling tapchanger operation on voltage regulating transformers includes a plurality of transducers to obtain real time voltage, wattage and reactive power readings, along with status readings for breakers associated with circuitry. A processor includes components to convert the analog transducer signals to digital signals, and process those signals utilizing preprogrammed and predetermined multipliers. A processor can read programmable files that dictate operational set points and ranges of set points. The software program allows evaluation of the real time actual parameter readings in comparison with set point and range set points to issue instructions to change the tapchangers on the transformers to maintain control of and regulate the voltage from the transformer. Other features and advantages are described herein.
