3 wire 3 phase ungrounded systems

Former Community Member over 5 years ago

I suspect I already know the answer but are 3 phase, 230 volt, 3 wire ungrounded systems permitted in a UK installation?

I know this is common practice in some parts of the world but it's not something I've come across in the UK.

Just for clarity this would entail a delta connected secondary with 230 V between phases requiring separate earth fault detection.

I wait with abated breath.

Many thanks for the inputs. I suspect it's not so much a case of specialist equipment and more a case of the author not researching the standards where the equipment is to be used. I think I'll follow my instinct and go for a rework inline with local (UK) standards.

Thanks to all
