I would be happy to be proven wrong... but I bet your transformer has a grounded neutral point with a dedicated conductor to your service panel, even if all your loads are phase to phase.
It could be corner grounded... but my understanding is that is very uncommon.
EDIT: I read your post again and I think "three phase" means "three wires": a 240V hot, a 0V neutral, and an earth wire?
- renewedrebecca 4y ago"three phase" generally means 3 hots, each 120 degrees out of phase with each other. You may or may not have a neutral with a 3 phase system.
- jcalvinowens 4y agoYeah. I thought maybe the author of that post was confusing "three wires" with "three phases". I don't know about the EU, but in the US there's almost always a grounded neutral point on three phase systems, even if the loads are all phase to phase. All the literature I've ever found says corner grounded deltas are "not to be used in new installations", and ungrounded deltas are similarly discouraged.
- renewedrebecca 4y agoAh, ok, that makes sense.
