    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??

    It depends on the job. Without a known goal, the word, "better" has no meaning.

    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.

    I mean if I have a source and a load and as you know that we have three phase system used today

    Again it depends on the nature of the load? The requirements can be different.!!

    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.
