Voltage Transfomer Size

230 VAC, 50/60 Hz, 3 phase, 16A/phase
(with 20 amp dedicated circuit breaker)

Hi Guys,
Please I need asap the power rating for a voltage transformer that can work perfectly with an equipment with the above specifications.

As the breaker 20A is not far from the load 16A, we can assume the worse case VA would be 20x230x3==13.8 kVA. This is the rating of your transformer.

You need to be sure you are actually drawing 16 or so amps, otherwise you will be oversizing the transformer. Also ensure you have no inrush currents or other special requirements which may affect the size of the transformer.
