Hello,
I work in a plant that has 3 phase 480 Wye as the primary service. All the people I've talked to about 240 3 phase, say that 240 3phase wye does NOT exist. I have a transformer in this plant that does just that. It transforms 480 3ph wye to 240 3ph wye. I have measured each phase-to-ground as 136V (there are no heavy loads on this transformer, hence the higher voltage) and each phase-to-phase as 233V. And yet, all of my electrical suppliers tell me I cannot get a transformer that does that. Do I just order a transformer that is 480 to 240 Dleta and reterminate the windings to a Wye config?
