Autors: Slavkova, M. D., Mintchev, M. S. Title: Influence of Magnetic Core Material on the Error of Current Transformers with Half-Wave Rectified Primary Current Keywords: current error, current transformers, half-wave rectified priAbstract: The purpose of the present work is to determine the influence of the magnetic core material on current error of current transformers with a half-wave rectified current. Based on this, the criteria for selection of an appropriate magnetic core material will be substantiated. The analysis is carried out by the software product PSpice. The results are compared with experimental data of the error of current transformers at differenet types of magnetic materials in the regime considered.
