Advice ref blinking lights all circuits

If it’s not on their side and it’s affecting everything on the load side then it’s inbetween lol

Check the tails, I’m still getting the tails are reversed polarity

 

[telectrix]

can't see reversed polarity causing it. a loose connection maybe.

Mmm. The point I was making is that as far as I know, nobody has connected a data logger yet.

Powergrid came out, inspected and setup voltage recording device and left that running for about 8 days.

I must admit I had to double check after your post! I'm interested if the problem actually occurred when the recording device was installed, as that would be different to "the recording device was installed but the problem didn't occur and they couldn't see anything wrong when they looked at the results".

I've also been wondering what the resolution of such a device would be, and would it be sufficient enough to detect a momentary glitch.

 

[DPG]

Doh. Sorry, I missed the bit about the supplier using a recording device sorry.

I'm with you on maybe it missing the briefest of glitches when they occur though. Would be good to see how well it picks up dips in the order of milliseconds.

Hi,

Yes, the problem occured while the recording device was installed. It was left on for 8 days. It was a Fluke device of some description, though couldn't tell you what. They said it would record voltage fluctuations.

I will try to take some photos over the weekend.

I'm thinking of getting a second opinion if the guys who carried out the work can't find anything when they come back on Thursday and if they insist it's a supply issue. I guess it could be purely coincidental that this only started happening within a week of the work taking place, but, because of that, I think it unlikely that it will prove to be a supply fault.

i regulary pick up dips. mmmmm.

How did the electrician isolate the supply to enable the new CU to be fitted safely?
If there is no double pole isolator fitted between the meter and CU I assume the main cut out fuse was removed after breaking the seals?
Before refitting the cut out fuse were the terminals checked and the fuse retaining screws checked for tightness?
Were all the cut out terminal screws checked for tightness?
If the cables from the meter to the CU were replaced were all the meter terminal screws checked for tightness?

Sorry to drag this old thread up, came across it when searching for GU10 polarity checking.

Was this ever resolved?

Is the circuit effected a two or more way switched one, if so perhaps the potential current in the permanent live charging the capacitor in the GU10 and discharging causing a flash.

As the OP was last on here 20 March 2018, there is not much chance of an answer.

 

[Mike Johnson]

I realise that, but thought as no conclusion was reached it may be helpful to resurrect the thread to see if knowledge of this type of problem had improved over the last eighteen months or so.

Plenty of people have come across this sort of problem....and corrected it successfully, generally finding a fault such as one of those already mentioned in the thread.

 

[Mike Johnson]

I cured the flashing in one set by the use of a capacitor across the terminals of one lamp, there was no fault to correct on this particular installation.

But this was general, throughout the house, not one lamp...or one circuit , even.……...anyway, it's all in the past

 

[Mike Johnson]

As far as I understood it started to happen when the OP changed one circuit to LED's from halogen, not generally throughout the house?

You’ve lost me there. Have you read the opening post?

 

[static zap]

Since I've had a power cut recently , I notice every flicker of my under powered lounge LED lamp.
(some of the more expensive Dimmable Lamps seem to smooth this out !)

I have re-read it and find that I was the one lost, not you, sorry for the miss-understanding.

We all do that sometimes, I wouldn't worry about it.

This is 'capacitive coupling' when a LED will flash or strobe at set intervals, likely every 1-2 seconds. The OP did say their flashes were completely random so unlikely to be the same kind of fault.

 

[Mike Johnson]

The ones I cured would flash at random times, sometimes as much as an hour apart.
