Note 1: For transformers with a rated capacity of 500kVA and below, the load loss values indicated above the diagonal line in the table are intended for the Dyn11 or Yzn11 coupling group. Conversely, the values found below the diagonal line serve the Yyn0 coupling group, promoting precise energy management.
Note 2: Maximize operational efficiency by employing the loss value outlined in the table when the transformer's average annual load rate falls between 35% and 40%. This thoughtful application of data ensures top-tier performance.
