Frequently Asked Questions

How do you size a three phase transformer?

  • Note the power of the appliance – usually in the appliance manual,
  • Note the voltage (240 volts in the UK).
  • Use the next highest fuse rating after the calculation. Say the calculated fuse rating is 2.2679 amps, use a 3 amp fuse.

What is the size of a 3 phase transformer?

Total kilovolt-ampere of the connected system is calculated including design margin and then the next available standard size will be selected. The typical standard size kilovolt-ampere for three-phase transformer based on ANSI C57.12.00 typically range between 15 and 100,000 kva which are based on the output of the transformer.

How to correctly size a transformer?

  • K ssc - rated symmetrical short-circuit current factor
  • K ’ ssc - effective symmetrical short-circuit current factor
  • K td - transient dimensioning factor

How to determine transformer size?

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.
