Автоматика отключения силовых трансформаторов на понизительных подстанциях в целях снижения технических потерь электроэнергии

To reduce idling losses in substations transformer groups with a low average load of transformers - turn off one of the transformers at a low actual load, and with a high load, switch on. The method of the effect calculation and the algorithm of automatic switching for multicriteria control are given.
