How can I find out the efficiency of my transformer ?

I would need to know the efficiency of my 1MVA, 12.47KV/480V transformer, like it is available on the quotation. How can we find it after buying the transformer ?

ABB's answer

The efficiency is directed by electrical standards for IEEE/NEMA products.
In the case you described in your question, the efficiency is 99.43% at 50% load.
Not all manufacturers will include efficiency details with their transformers.
You can find any information on transformer efficiency on our dedicated portal
You can also compare transformer efficiency with ABB’s TCO Tool
