hi!!

wye-delta transformers are used as grounding transformers in ungrounded power systems, which is aside from zigzag transformers.

you will observe that it has secondary winding of delta.. which will trap the zero sequence currents

hope it helps.. God bless

Not necessarily! Wye-Delta transformers have been widely used as Power Transformers too!
