Abstract
A new electronic system to assist high-voltage measuring transformers is proposed. This system compensates the voltage drops in the series impedances, which are the main cause of error in this type of transformer. An adjustment procedure is proposed using a power analyzer as the zero detector. The nonlinear behavior of the magnetizing branch has no influence on the results.
