• 9910A High Voltage Capacitance Bridge is a measurement standard employing the AC Current Comparator principle. The Current Comparator principle is applied to the measurement of ratio and dissipation factors of high voltage capacitors in a similar manner to the classical Schering Bridge but with greatly improved accuracy and resolution. The Model 9910A High Voltage Capacitance and Inductance Bridge brings the superior accuracy of the Current Comparator to those applications too stringent or demanding for conventional Schering Bridges. Referred to an external gas-filled standard capacitor, accuracy and resolution are better than 15 ppm. The instrument is ideally suitable for low-cost, high voltage, power cable measurements.
