Description
Summary:The article discusses the characteristics of the joint operation of current transformers (CTs) of various accuracy classes with advanced algorithms for the differential protection of a microprocessor-based transformers. The issues of modern differential protection of transformer algorithms are presented, as well as means to address them, both using CTs with air gaps and improving their algorithms.
