Welcome to the IEC 60044-1 – Current Transformers: Accuracy, Testing & Applications course. This comprehensive training course is designed to provide electrical engineers, technicians, testing and commissioning professionals, protection engineers, metering specialists, and students with a practical understanding of Current Transformers (CTs) and the technical requirements associated with IEC 60044-1. Current Transformers are essential components in electrical power systems, providing scaled-down current signals for measurement, metering, protection, and control applications. The accuracy and performance of a CT can directly influence the reliability of measurement systems and the correct operation of protection equipment.
Throughout this course, you will develop an understanding of important CT concepts, including CT construction and operation, accuracy classes, current error, phase displacement, rated burden, excitation characteristics, composite error, metering applications, protection applications, and CT testing principles. The course also explains how CT performance is evaluated and why parameters such as burden, excitation current, accuracy, and saturation characteristics are important when selecting and testing a Current Transformer.
Special attention is given to understanding the difference between measurement CTs and protection CTs, and how their performance requirements relate to their intended applications. You will also learn how to understand CT technical specifications and interpret relevant test information.
