IEEE C57.105-2019 IEEE Approved Draft Guide for Application of Transformer Connections in Three-Phase Electrical Systems

IEEE C57.105-2019 IEEE одобрил проект Руководства по применению Трансформаторных соединений в трехфазной электрической системе

This guide describes transformer connections and configurations in 3-phase electrical systems. The characteristics of the various transformer connections and possible operating problems under normal or abnormal conditions are treated. All combinations of delta and wye, grounded and ungrounded, T connected, zigzag, and certain special connections are considered. Only two-winding and auto-transformers are included.
