How can I get 220 Volt 3 phase ?
 

Please I am fixing a small machine but the voltage to machine from
the US is not standard over here. The 3 phase we have here is 415
volts but this machine is rated 220 volt 3 phase (it has a 3 phase
motor). The problem is how do I get the 220 v 3 phase? In fact I used
3 separate auto transformers (not too similar) I observed the polarity
and connected it in Delta - Star but any time I put in power it
blows. I want to know whether the auto transformer is not suitable or
I should use an isolated primary and secondary winding transformer.
Apart from using a single 3 phase transformer is there any other
Method? Thanks
