What is the configuration (Wye, Delta or some combination of the two) for this three-phase circuit?

Here is the circuit.: https://www.docdroid.net/RTLST6g/output.pdf Also, how does one determine that? I think that it's a Wye-Delta configuration because the voltage sources are connected at a common point and each of the impedances are connected to the other two impedances. Is my reasoning correct?

Any input would be GREATLY appreciated!
