Study of the effect of temperature on the metrological characteristics of Inductive Current Transformers

The presented thesis focused on the study of effect of temperature and different loading condition of an inductive current transformer for medium voltage purposes. Equivalent circuit parameters behavior of the current transformer is analyzed for two different temperatures 24°C and 60°C and varying working conditions (current and voltage). Application of Short Circuit and Open circuit test is done for the current transformer under test with varying loading conditions and two temperatures of interest. Interesting behavior of the shunt parameters of the current transformers are of most attention and can be implemented during modeling a current transformer.
