Hello guys , how are you?

I studied that there are two types of balanced three phase circuits, that are star and delta .Which can be used as a source- such as a transformer- or as load.

which of them is better to be a source and which is better to be a load and why??

If you only need three phase with without the need for using any particular phase as say a 1ph and Star neutral then Delta would be the way to go.
The Star (Wye) gives you the option of a grounded neutral system.

Star will give higher current at lower line voltage, delta will give lower current at higher line voltage, both will give the same power output.
