Transformer Calculator KVA Calculator Full Load 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. When the KVA rating has been calculated, divide that number by 0.8 to get the minimum KVA rating needed.
