  • Transformer Calculator KVA Calculator Full Load Amps ...Explore further

    Transformer calculator HOW TO SIZE A TRANSFORMER. Transformers are sized by determining the total load required (in amps). Transformer capacity is rated in KVA (kilo-volt-amperes). The load voltage and load amps must be known to calculate KVA rating. * NOTE: We do not recommend loading a transformer above 80% of its KVA rating.
