Note 1: For transformers with rated capacity of 500kVA and below, the diagonal line within the table reveals its secrets. Above it, the Dyn11 or Yzn11 coupling group reigns with specific load loss values, while below, the Yyn0 coupling group finds its match.

Note 2: Unlock the potential for maximum operational efficiency! When the transformer's average annual load rate is nestled between 35% and 40%, the table's loss values guide the way to peak performance.
