Abstract

Working standards for dissipation factor (D) obtained by connecting a shielded three-terminal capacitor in series with a shielded precision resistor have been developed for calibration purposes. Precision conductance boxes have been built for use with a single three-terminal 1000 pF gas capacitor standard to create dissipation factor standards having values from 2×10^-5 to 1×10^-2. The design and testing of these D standards, including precautions in their construction and use, is presented. Calibration procedures using the NIST high voltage capacitance bridge and the measurement uncertainties are discussed
