Abstract :
A new electronic system to assist high-voltage measuring transformers is proposed. This system compensates the voltage drops in the series impedances of the transformer, which are the main cause of errors at power frequency. The nonlinear behavior of the magnetizing branch has no influence on the results. The proposed compensator also reduces the influence of the burden impedance on the transformer errors. It is not necessary any auxiliary winding or core, so that conventional units can be compensated
