Re: Strange neutral voltage
bunched cables creating a ghost voltage?
Re: Strange neutral voltage
I have sat and thought that tonight, it's cabled in SY if that makes any difference.
Re: Strange neutral voltage
I think you have lost a phase
Re: Strange neutral voltage
if the sy is run parallel to cable- like in galv trunking with singles then it could pick up interference, run a temporary cable along the floor to prove this- had it on a burner- got 73v neutral to earth- panel was 6mtr away
Re: Strange neutral voltage
Check what voltages you get between phases, all should be the same. The site step down transformer probably does not have a neutral to earth link on the secondary side. So you get weird voltages between neutral and earth, particularly if using a digital multi-meter, try it with an analogue meter. Get a registered electrician to do a loop impedance test to be doubly sure. Also I have had situation that one transformer coil was playing up and needed rebalancing but that generally occurs under load conditions.
Re: Strange neutral voltage
Thanks for the help lads, will update as I make some progress!
Re: Strange neutral voltage
Evening all,
Problem is now sorted. Ran a new cable in which solved the neutral problem(28m down a dry riser mind!!! All good fun!!!) Only to find e32 fault still. Switched a couple of phases and gone!
Thanks for the help lads, much appreciated as always!
