Dear Guest,

I don't know whether 1 phase transformer has Vector Group or Not.

as long as i know, Vector Group is for three phase transformer. For Example :

DYn11 (Delta on primary side, Wye on secondary side), DYn1..etc

Thanks

Hello everyone ,

for single transformer you can make O or 6 hours vector group. It is very important , for example, for connection secondary circuit of current transformer for differential protection of big motor or power transformer .

Good luck !
