Voltage Regulator
Selection Guide
Standard Specification
GE Voltage Regulators are tap-changing autotransformers with the capability of continuously monitoring system output
voltage and automatically correcting by boosting or bucking the output voltage with respect to the input voltage. Refer
to Tables 1 and 2 for detailed regulator rating information for typical 50 Hz and 60 Hz designs. For additional information,
contact your GE representative.
The GE Voltage Regulator is designed and manufactured in accordance with the latest applicable ANSI, ASTM, RUS, CSA,
IEC, and NEMA standards. ANSI Type A and B construction provided based on rating.
