PARALLEL OPERATION
PARALLEL OPERATION111. Parallel operation of transformers. Transformers will operate satisfactorily in parallel (Fig. 5.68), i.e., with their high- and low-tension windings respectively connected directly to the same circuits, provided that they have (1) the same ratio of transformation, (2) the same voltage ratings, and (3) approximately the same regulation. If the low-tension voltages are different, the transformer having the highest voltages will circulate current to those of lower voltage and cause a continuous loss. If transformers connected in parallel do not have the same regulation, they will not share the total load in proportion to their ratings. The greater share of the load will be ta…
