A portable error simulator for evaluating voltage transformer test set(VTTS) using a voltage divider consisting the serial combination of the resistor and capacitor was developed. The error simulator was applied to the calibration of several type commercial current-comparator-based VTTS and covered the ratio error and phase error range up to ±10 % and ±15 crad, respectively. From the calculated and...
A capacitor-resistor combined bank to calibrate both the capacitance ratio and dissipation factor of the commercial capacitance and tan δ measuring bridge is fabricated. The fabricated portable working standards as a secondary standard for ratio calibration are realized by connecting the double shielded capacitors in parallel employing the substitution and build-up technique, whereas, the standards...
