If we have a three phase circuit, where source voltages are in a delta configuration, like the one in the picture:

enter image description here

What is the difference between phase and line voltages in this case?

When generators are in a starwye configuration, we know that line voltages are defined as: \$E_{12}=E_1-E_2\$, but here, line voltages are simply: \$E_1, E_2\$ and \$E_3\$. What are phase voltages then?
