parallel transformers

[saw]

Hi There,

Does anyone know the answer for question below?

two transformers are connected in parallel. both have delta primary and wye as secondary. That means delta connected to delta and wye is connected to wye. Is this connection okay or it will cause circulating current? I appreciate any response. Thanks
