Before you check voltage in a 3 panel panel. Does the electrican or engineer need to understand Wye or Delta configurations? Or does it only apply to transformers?

No, the three phase system applies to all three phase systems like transformers, motors, heaters, ovens, electrical appliances, stuff, things and bicycles which are three phase.
