  • Spreadsheet for Transformer Losses Calculation

    2021-9-13 · These losses, also known as no-load losses, are present all the time the transformer is powered on – regardless of whether there is any load or not.. Core losses are roughly constant from no-load to full-load when feeding linear loads. They represent a continuous cost, 24 hours/day, for the 25-year or more life of the transformer.
