A new error compensation method of inductive voltage divider

This paper describes a new error compensation method based on the transformer principle. The method makes use of the voltage transformer being connected in parallel to input of IVD to provide n voltage value of n times 10^-8, which can respectively compensate in-phase error and quadrature error of each output tap voltage of IVD by regulating n. After compensation, the accuracy of IVD can stably achieve n times 10^-8.
