Web208, 240 and 480 are all common 3 phase systems. Just because your house has 240 single phase doesn't mean there isn't any 240 3 phase systems. 4. larz_6446 • 2 yr. ago. 230 is also a 3 phase system voltage that comes in a couple of different flavors: Corner grounded Delta, or a mid point grounded Delta with the B phase bastard leg. 3. Webthis is the correct answer. I work in a utility with an ungrounded Delta system. This is exactly what happens when one phase goes to ground. the phase to phase voltage is unchanged, but the phase to ground voltage on the grounded phase will read 0 volts and the phase to ground voltage on the other two phases will read proportionately higher.
