A high-precision transformer bridge for the measurement of capacitance and loss-angle tangent over wide dynamic and frequency ranges is described. The bridge construction is based on the principle of variational calibration, which enables us to exclude the effect of the error sources on the measurement results. The principal measurement error of the capacitance does not exceed 10–6.
