Evaluation of Errors of Electronic Voltage Transformer using High Voltage Capacitance Bridge and Standard Capacitive divider

고전압 전기용량 브지리와 표준용량분압기를 이용한 전자식 전압변성기의 평가

We established a system to evaluate the ratio error and phase angle error of electronic voltage transformer using high voltage capacitance bridge and standard capacitors. The uncertainty of evaluation system is about 0.005% in ratio error and 1.5 min in phase angel error.
