high voltage on the neutral
high voltage on the neutral
(OP)
For 4-wire multigrounded distribution circuits, what types of faults on a distribution feeder can produce high voltages on the neutral?
By high, I mean something more than 150 V. I'm just looking at what faults can possibly result in high voltages at a residence. I know open neutrals can exceed this, but I'm focusing on just primary faults.

The circuit was eventually cleared at the substation. I don't have any documentation. The investigating engineer was a personal friend of mine and we discussed his findings at length.

RE: high voltage on the neutral
In rereading what I posted, I mispoke about the half voltage. With a phase to neutral fault, a sizeable part of the drop will be through the substation transformer and the source impedance behind it. What I meant to say is the remainder of the voltage drop will divide about equally if the phase and neutral wires are the same.
