Notes:

1. For transformers with a rated capacity of 500 kVA and below, the load loss values above the slash in the table apply to the Dyn11 or Yzn11 vector group, and the load loss values below the slash apply to the Yyn0 vector group.

2. When the annual average load factor of the transformer is between 35% and 40%, the loss values in the table can achieve the highest operating efficiency.
