1000KVA transformer no-load loss is how much?
No-load loss is 1% of the rated capacity of the transformer, then 10KVA per hour. A year down about the loss is 87600KVA.
I am in the "China Electromechanical Product Catalog" found a data, 10KV, S9-1000KVA no-load loss is 1.7KW, so the annual loss of power: 1.7 * 8760 = 14892KWH (degrees).
Transformer no-load loss is not the same, not only the manufacturers are not the same, is a manufacturer at the same time manufacturing two transformers, may be no load loss will not be exactly the same;
Different types of transformer no-load loss is not the same, the larger the model, the smaller the no-load loss, such as S9 than the S7 no-load loss is small.
