The wye common point connection makes this a neutral point three phase cycle has 1 moments in any second in time when a sine wave is crossing zero volts in the cycle of the sine wave each phase is at a point the voltage will not be 240 volts but 8 volts on a wye transformer basically there not at the same peaks or points in time so its less voltage between phasesThis may be a bit confusing, but there is no such voltage in a 3phase 4wire system, rather the voltage exists only because the Neutral is commonly bonded to ground The confusion arises, in part, because "ground" has two very different meaningFind it at Graingercom®
