Abstract :
The traceability chain to derive the capacitance unit from the quantized Hall resistance (QHR) comprises a few coaxial bridges. These bridges use a main two-stage, guarded inductive voltage divider (IVD) to provide the voltage ratio. The design details and calibration results of the IVD constructed partly at INMETRO and partly at PTB, with technical support from PTB and CENAM, are presented
