Bad information There is no 'neutral' in three phase.That's Good question...!!
Just for checking grounding you have to use Multimeter connect one probe of meter to ground and other to neutral note reading, then check live and neutral voltage.
on comparing then you can know the quality of groundong.
Ideally it is 0V ..
just as 'bad'. there may be a grounded center tap in a delta, and the central point of a wye may be brought out, in which case code requires it to be grounded. both being three phase.Bad information There is no 'neutral' in three phase.
But like I said there is no 'neutral'. Ground is not considered neutral. With three phase there are three 'hots' and ground.just as 'bad'. there may be a grounded center tap in a delta, and the central point of a wye may be brought out, in which case code requires it to be grounded. both being three phase.
Not so in the case of a wye with center brought out. You may be thinking 3 phase/ 3 wire, but 4 wire systems are very common.But like I said there is no 'neutral'. Ground is not considered neutral. With three phase there are three 'hots' and ground.
