– 800kVA : Po : 2470W, Pt(+70°C) : 8370W
– 1000kVA : Po : 2940W, Pt(+70°C) : 9800W
– 1250kVA : Po : 3520W, Pt(+70°C) : 11800W
– 1600kVA : Po : 3890W, Pt(+70°C) : 14400W
– 2000kVA : Po : 4830W, Pt(+70°C) : 17100W
– 2500kVA : Po : 5990W, Pt(+70°C) : 20700W
– 3200kVA : Po : 4600W, Pt(+70°C) : 23400W
For ” 33 kV ” :
– 630kVA : Po : 2100W, Pt(+70°C) : 6750W
– 800kVA : Po : 2580W, Pt(+70°C) : 8370W
– 1000kVA : Po : 2800W, Pt(+70°C) : 9280W
– 1250kVA : Po : 3000W, Pt(+70°C) : 12350W
– 1600kVA : Po : 3600W, Pt(+70°C) : 14600W
– 2000kVA : Po : 4600W, Pt(+70°C) : 16200W
– 2500kVA : Po : 5780W, Pt(+70°C) : 19800W
– 3200kVA : Po : 6620W, Pt(+70°C) : 22500W
Where :
– Po : the Losses without load
– Pt(+70°C) : the losses with ful load at ” +70°C “
Noting that values are for ” Zucchini – Italy ” transformers, and there's some differences between manufactures.
