本指南介绍了IEEE Std C57中所述的三次绕组和稳定绕组在液浸式电力变压器中的应用。12.00，以及评估此类绕组的必要性或便利性的建议。本指南主要适用于带Y形连接绕组的变压器和自耦变压器，带或不带三角形连接三次绕组或稳定绕组。本指南不涉及传统三角形Y形管或三角形Y形管中的三次绕组- 三角形连接的变压器。

This guide addresses 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. 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. The guide does not address tertiary windings in conventional delta-wye, or delta-deltaconnected transformers.
