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 ?
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
If you want to purchase a product, need any pricing information or need help or support from ABB, please contact your local partner.
