This paper presents a study focused on the equivalent parameters of an inductive current transformer for medium voltage purposes. In particular, its equivalent parameters behaviour has been assessed by varying both the temperature and the working conditions (current and voltage). Preliminary results provide interesting “calibration” curves which may be used during the transformer modelling
