I am looking to find the rated amps for the sencondary of a stepdown transformer. Three phase primary is 460/575V, secondary 230V, 200VA. I am not sure if I should calculate the secondary side of the transformer as 3 phase or single since it is only 2 wires coming out of the secondary.
3 phase- 200/230/1.73= .5 Amps
Single Phase- 200/230= .87 Amps
I am not sure which is correct and I could really use the help thanks.
