To get a conversion of 230V to 460V 3 phase you will need either a. three phase transformer with a KVA rating high enough to handle the. total load of the motor or motors you plan to use. If the motors are. rated in KW just add the individual motor ratings and use an. equivalent transformer.
In Febuary, while working the NAAM music trade show in Anaheim, CA, I installed a 120v 60Hz primary to 230v 50Hz sencondary boost transformer for a European sound & music equipment booth, from England. This shobox size xfmr was spec.'d by the equipment Mfg., and provided by the client at the booth.
An option how to make 230 VAC delta motor out of 400 VAC star 3-phase asynchronous motor.
When the KVA rating has been calculated, divide that number by 0.8 to get the minimum KVA rating needed. All values should be reviewed and confirmed by an electrician or electrical engineer. NOTE: If you need assistance with circuit protection devices such as fuses or breakers, or wire sizing, please consult a licensed electrical contractor or

For Single phase 230v any of your phase i.e. Gray Black Brown and neutral = Single phase 230v However to derive Single phase 400v = connecting gray and black without the neutral to the Load This is still single phase because one of the cable is acting as neutral i.e. a return path back to the substation I hope this helps.

Transformer Rating = 50 kVA = V 1 × I 1 = V 2 × I 2. Primary full-load current, I 1 = (50 × 1000 / 4000) = 12.5 A. Secondary full-load current, I 2 = (50 × 1000 / 400) = 125 A. b) Turns Ratio = N 1 / N 2 = V 1 / V 2 = (4000 / 400) = 10.
