240V RMS / Sqrt(3) = 139V RMS. You could call it 220/127V or 230/133V if you wanted to, all depends where in the distribution system it is, what with voltage drop at all.

Pole pigs aren't high leg delta, as least not normal 1-phase residential ones. They're a single center-tap step-down transformer that drops the line voltage to 240V with a grounded center-tap for the neutral.
