PARALLEL OPERATION OF SINGLE-PHASE TRANSFORMERS The necessity of parallel operation of transformers is felt when the amount of power to be transformed is greater than that which can be handled by one transformer. The important conditions which must be fulfilled if two or more transformers are to operate successfully in parallel to deliver a common load are
These conditions are most easily met by paralleling transformers of identical ratings of the same make and model. Careful study must be performed with different kVA ratings of even the same make or the effects in steps 1, 3 and 4 may appear in undesirable amounts. Step 2 has to be strictly observed even it steps 1, 3 and 4 are slightly modified. | |
