Note 1: For transformers with rated capacity of 500KV·A and below, the load loss values above the diagonal line in the table are applicable to Dyn11 coupling group, and the load loss values below the diagonal line are applicable to Yyn0 coupling group.
Note 2: When the annual average load ratio of the transformer is between 30% and 36%, the highest operating efficiency can be obtained by adopting the loss values in the table.
