电力系统中常采用三绕组自耦变压器作为联络变压器，以减少***和运行费用。它有高压、中压和低压3个绕组。通常其高压和中压侧均为110千伏以上的系统。其运行方式有以下5种。
自耦变压器
①高压侧向中压侧或中压侧向高压侧送电，如图2a所示。实线方向为高压侧向中压侧送电，虚线表示中压侧向高压侧送电。因为高中低三个绕组与铁心的相对位置，在制造时与设计有所差异，所以在这种运行方式下，如果中压布置在高低压之间，一般可以传输全部额定容量；如果中压绕组靠铁心布置，则由于漏磁通在结构中会引起较大的附加损耗，其***大传输功率s往往限制在额定容量S1n的70～80%。
②高压侧向低压侧或低压侧向高压侧送电，如图2b所示。此时功率全部通过磁路传输，其***大传输功率不得超过低压绕组的额定容量S3n。
③中压侧向低压侧或低压侧向中压侧送电，如图2c所示。这种情况与第 2种运行方式相同。
④高压侧同时向中压侧和低压侧或低压侧和中压侧同时向高压侧送电，如图2d所示。在这种运行方式下，***大允许的传输功率不得超过自耦变压器高压绕组（即串联绕组）的额定容量。
⑤中压侧同时向高压侧和低压侧或高压侧和低压侧同时向中压侧送电，如图2e所示。在这种运行方式中，中压绕组（即公共绕组）为原绕组，而其他两个为副绕组。因此，***大传输功率受公共绕组容量的限制。
