Abstract :
Characterization of five accuracy class 0.2 current transformers rated 600 A up to 2500 A is done by measurement of phase displacement and amplitude error as function of frequency and current. The test system is presented and the test procedure is described. The accuracy of test system voltage and current measurements is addressed and separate measurements on the transformer burden (load resistance) are carried using other test equipment. This enables an assessment of the test equipment measurement ability. Finally, measurements of the current error and phase displacement of five different current transformers with burden are carried out
