Analysis of Selection Criteria for Rated Secondary Current of Current Transformers

Analysis of Selection Criteria for Rated Secondary Current of Current Transformers

The selection of a CT’s rated secondary current is a multifaceted decision that impacts system accuracy, efficiency, and cost. While 5 A remains dominant in LV systems and regions following ANSI standards, 1 A is preferred for HV applications, long cable runs, and IEC-compliant systems due to its lower losses and improved efficiency. By systematically evaluating compatibility, power loss, accuracy, fault handling, and cost, engineers can select the optimal rating to ensure reliable and economical operation of power systems.
