Discuss electric meter issue. The grid, meter or consumer unit issue? in the UK Electrical Forum area at ElectriciansForums.net
SC said 'loose connection' in the DNO's equipment in post #2 and I totally agree. A loose connection in the service cable joint for example. But others have gone on to be more specific by saying it's the neutral. Why? What evidence do we have that the neutral is faulty and not the line?

We've had a discussion with lots of good ideas about why high resistance connections are (thought to be) more common in neutrals, specifically in domestic installation work. Explanations include sparks habitually wiring the line first, then doing the neutral with waning concentration; or manufacturers using terminals of inferior design in CU neutral bars, etc. But does this apply to DNO equipment too, such as service cable joints? Where CNEs are terminated they have to be extra vigilant about continuity, so I'd almost expect a higher rate of failure in line connections.
Thoughts?
OP: I'd call the DNO. The problem is theirs, not yours, the meter display showing 'Low U' is a dead giveaway.
Fantastic!Thanks for all your input guys. The grid guys came out last night and repaired it. It was a faulty Neutral
Hi Rob! That's something beyond my area of expertise .... What is a "K Type transformer?" Or are you just saying it's a tx rated for a K factor of 2?Most DNOs as standard are fitting K Type transformers now with a 200% FLC rated star point connection.

It was outside my house on the footpath. It looked like quite a big job.
Do you think this fault could re-occur or once fixed is that more or less, "job done"?
Brilliant video, well done! I also think you've been quite lucky to get away with none of your delicate electronic equipment failing as the original supply must have been very dirty.Do you think this fault could re-occur or once fixed is that more or less, "job done"?
