Electronic-Based High-Voltage Measuring Transformers

IEEE Power Engineering Review, 2002
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.
