The zero-flux current transformer is also called a magnetic balance current transformer. Based on the electromagnetic induction principle, the theoretical error of the zero-flux current transformer is equal to zero, and there is no ratio difference and angle difference. In order to eliminate the influence of the excitation current on the measurement accuracy, the zero-flux current transf...
