Abstract

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 for dissipation calibration are attained by connecting shielded capacitors in parallel with a shielded T-resistor network. The calibration results for the several commercial bridges are presented and compared with specification provided by manufacturer including the measurement uncertainty.
