Guide for the Application of Tertiary and Stabilizing Windings in Power Transformers

This guide addresses the application of tertiary and stabilizing windings in liquid-immersed power transformers, as covered by C57.12.00 "IEEE Std for General Requirements for Liquid-Immersed Distribution, Power, and Regulating Transformers", as well as recommendations to evaluate the need or convenience of having such windings. The primary application of this guide is for transformers and autotransformers with wye-wye-connected (also known as "star to star" connected) windings, with or without a delta-connected tertiary or stabilizing winding. The guide does not address tertiary windings in conventional delta-wye, or delta-delta connected transformers.

C57.158-2017
IEEE Guide for the Application of Tertiary and Stabilizing Windings in Power Transformers

The application of tertiary and stabilizing windings in liquid-immersed power transformers, as covered by IEEE Std C57.12.00™, as well as recommendations to evaluate the need or convenience of having such windings, are addressed in this guide. The primary application of this guide is for transformers and autotransformers with wye-wye-connected windings, with or without a delta-connected tertiary or stabilizing winding. Tertiary windings in conventional delta-wye and delta-deltau2013connected transformers are not addressed by this guide.
