Note: 1. For transformers with rated capacity of 500kVA and below, the load loss value above the slash in the table is applicable to Dyn11 connection group, and the load loss value below the slash is applicable to Yyn0 connection group.

2. The loss parameters in the table are also applicable to the three-phase transformer with high-voltage dual-voltage 20(10).
