Procedure and universal winding of higher voltage of three-phase transformers, for voltage levels X and 2X. For this type of winding, as distinguished from standard accomplishements, one regulator is required. By adding two more outlets for regulation and by suitable directions of winding, semiwinding is obtained a re-tie transformator, that is applicable for any voltages, where at the side of high voltage the voltage ratio is 1: 2 (or vice versa). It is particularly important for electrodistribution networks the voltage of which is 10kV and 20 kV. |
