Routine Testing–Oriented Method for Evaluating Inductive Current Transformers Accuracy Under Harmonic Distortion, Based on Maximum Current Error and Phase Displacement

IEEE Access
In the case of the modern inductive current transformers the most important factor that have influence on their wideband accuracy is the self-distortion of the secondary current caused by the nonlinearity of the magnetization characteristic of the ...
