Note 1: For transformers with a rated capacity of 500kVA and below, load loss values above the diagonal line in the table pertain to the Dyn11 or Yzn11 coupling group, while those below cater to the Yyn0 coupling group. This setup ensures versatility and efficient energy management.
Note 2: With the transformer's average annual load rate ranging from 35% to 40%, optimal operational efficiency is within reach by strategically employing the loss value specified in the table, thus enhancing the transformer's performance capabilities.
