Weird Linky issue

Property & Home

I am facing a weird problem with my Linky meter. Was wondering someone has faced it too.

If there is a big sound or something e.g. drilling, thunder etc it switches itself off automatically sometimes. Switch it on back again and it works just fine. Once I was away and it turned itself off and I came to an awesome smell in my fridge and freezer.

When the electrician was installing the radiators, the meter switched off couple of times. Then in the recent thunderstorms it switched off. I went outside just to check if lightning was nearby but it was quite far away.

More context is required here.

When you say that the Linky switches off do you mean that the meter itself cuts the power (& requires resetting) or is the main disjoncteur différentiel switching off?

The former can only happen if you exceed the maximum power level you subscribe to; the latter can also do that but, more importantly, drops out in the event of a major fault current.

P.S. If my description isn’t helpful maybe send a picture of what trips off &/or the message on the Linky screen.

Thanks for that, saw the name on the thing. Yes that is what happens. Mine is an old knob style one.

And I am on 9kVA and there is no way I am going over it. Or that is what I assume. I will need to switch on all my radiators and oven to just get over my max current.

So 'nowt to do with the Linky itself.

It sounds as if you have something faulty somewhere. That main DD will trip either through overload or if there is a fault current (or culmination of fault currents) in excess of 500mA.

If all your end user circuits are protected via 30mA différentiels (which they should be) then there could be a fault upstream of those, possibly inside the tableau or in the private supply cable from the main DD to your main tableau (or possibly in the supplies to further tableaux elsewhere, if you have them).

If the fault is genuinely triggered by sound then it suggests a dodgy connection somewhere that shifts slightly with vibration (or the object that has pierced a cable moving…).

Posting pictures of your tableau(x) with covers off would be helpful in diagnosing this, but it will be better to get a competent person with proper test equipment involved.
