Abstract :
A measurement system for capacitance traceability based on quantized Hall resistance (QHR) has been established at Center for Measurement Standards (CMS), Taiwan. The system comprises an ac-dc calculable resistor, an ac resistance bridge, a capacitance bridge, and a multi-frequency quadrature bridge. By using the multi-frequency quadrature bridge, the capacitance standards can be precisely determined at frequencies from 500 Hz to 5 kHz
