IEEE Approved Draft Guide for Application of Transformer Connections in Three-Phase Electrical Systems - Corrigendum 1: Update Table 1--Application characteristics of connections

This guide describes transformer connections and configurations in three-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.
