Abstract A set of coaxial resistive voltage dividers (RVDs) with serial-parallel connection was designed, and a new method was also proposed to calibrate phase angle errors of RVDs at frequencies up to 100 kHz.The method was mainly based on a special proportional relationship with the resistance and capacitance between two RVDs with identical structure.The absolute phase angle error of a RVD can be derived from the phase difference between the two RVDs.The RVD with ratio of 100:1 consisting of 100 Ω resistive elements was built and self-calibrated with the new method at frequencies from 400 Hz to 100 kHz.The measurement uncertainties was also evaluated.The standard uncertainty in phase angle error of the 1001 RVD consisting of 100 Ω resistive elements was within 30 μrad at 100 kHz.
