480 volt DS

[*]A to Ground 451 volts

[*]B to Ground 0 volts.

[*]C to Ground 447 volts

[*]A to B 480 volts

[*]B to C 480 volts

[*]C to A 480 volts
[/LIST]
Now do you see the problem?

The only problem I see is if A & C to ground is lower then the phase to phase voltages. Where is the missing voltages?
It should have shown up in the B to ground reading depending upon the reference point of measurement?

Is that a typo? Shouldn't it be A->G = 480V

Yep. ...............
