Generators!!

Why the electrical generators are always connected in delta?

Who says they aren't?

Perhaps because for a given load, the currents are higher in delta, and copper is expensive and heavy?

Whether connected delta or wye, the same amount of copper (in principle) is required for a given kVA rating. Insulation thickness and other factors may have a second order effect on how efficiently the copper can be used.

Capacitive impedances between conductor and ground are relatively high so ground faults in a delta machine can result in appreciable current at the fault point- chewing holes in the iron and the conductor but low enough not to be easily detected. If you do have a fault it is better to be able to detect it quickly and clear it quickly. In addition there is some actual cost advantage to a Y connection- particularly at higher voltages.
All in all, the choice is made on the basis of actual experience.

Why would they need to be? You could have the generator wired in Star/Wye and the load wired in Delta.

--------------------------------------- They aren't. Probably more are connected Y.
