I think I may stand to be corrected, guys, but how does the linky make the disjoncteur trip?

This is what Robert contributed to the linked article:

For Elsie's 6 kVA example of a nominal current of 30 amps you would get 39 amps effectively, much more than the 26.09 amps for Linky. A tolerant behaviour of these old disjoncteurs also for surge currents, switch on of an electrical motor or heater (washing machine). The new Linky smart meters are electronic sharp shooters: do not pass your nominal current limit or....trespassers not allowed.

The 39 amps is precisely what all of my disjoncteur de branchements tripped at when tested and is the figure stored in the memory of the compteur CBE.

Enedis know these figures, they are uploaded with every meter reading in case someone has removed the seals and upped their puissance, they can also tell if the capot has been removed from the meter.

When the "technician" (who 3 months ago was working at Macdos) does the Linky upgrade he will have the maximum recorded current consumption on his jobsheet and will then try and convince the customer to up their puissao=nce souscrite which is surprise suprise free if he does it there and then and will be chargeable otherwise, pretty sure they get a bonus for each customer that accepts.

The disjoncteur de branchement is still there, as an emergency switch, one move to switch off everything. It's differential tripping mechanism (500 mA) is also there, but when installing the smart meter the ENEDIS technician or subcontractor silences it's overload/short function. Because clever electronics on board of LINKY take care of that. There is a range of specialised chips on the world market, only a few producers, allowing national power providers a choise of measuring techniques inside their smart meters. Switching off: essentially a simple relay, see picture as published by cpchardware.

I didn't know that so many thanks for the info/education.

3.5 years ago .. when our Linky was installed by a super-duper, qualified electrician .. he replaced our 'faulty' disjoncteur at the same time.
This came about when he asked me if we had had problems with the disjoncteur cutting our power, even tho we were using nowhere near our full 9kw at the time it would cut out.
When I replied that 'yes' the power cut out seemingly at random, he nodded and said he suspected as much as the readings it was giving on his screen were off-kilter.
So, after a new Linky, plus a new 'disjoncteur' we could, at last, have peaceful evenings with no need to reset the trip. Yay ☺.
EDF had previously said, on two occasions, that their electricians had found nowt wrong with our disjoncteur. Yea right.

Linky rules.

Though .. give the super electrician his due it was probably down to his splendidly caring character plus his glaringly obvious electrical ability.

All goes to show how useful a degree and a phd in electrical engineering from fifty years ago is for coping with modern electrical systems. :-)

:D As RA says Linky takes over the job of cutting off your supply if you use too much lecy. Here is the reset procedure...

Si votre compteur Linky affiche le message « PUISS DEPASSEE », cela signifie qu’il y a eu un dépassement de puissance. Dans ce cas, pour faire revenir le courant, vous devez débrancher ou arrêter des appareils électriques pour réduire votre besoin de puissance, puis appuyer au moins 2 secondes sur le bouton « + ».
Here’s a good rule of thumb:

That may be the theory (and I think it was the case when the Linky was installed in our garage), but in our apartment, the disjoncteur de branchement is inside the apartment, while the meter is in a cupboard of the building foyer, along with the meters of the other apartments. The technician did not enter our apartment when installing the Linky, he just got us to sign the paperwork at the door.

And that was the problem I had with accepting the Linkys for my appartements, they even insisted that the compteurs and disjoncteurs have an enclosure aorund them with locked doors using an EDF normalised lock, albeit one that could be opened with a screwdriver or strong key blade.

Any of the renters using too much current (usually from having brought in a fan heater) would have to walk down to the ground floor (I have emergency lighting) find the correct Linky amongst 8 platines and reset it, given that I have so many foreign non French speaking customers I cannot allow that situation.

To conform with the normes the 500ma disjoncteurs are all in the colonne collectif on the ground floor beside the meters so that was always a problem that I had to address with my design.

In each appartement there is a secondary identical disjoncteur but not type S as in the colonne set to the same rating, I was counting on them all being made to very fine tolerances and the theory was that due to the small voltage drop allowed from the colonne (1.5% IIRC) the actual current drawn by the disjoncteurs in the appartements would be slightly higher than their upstream twins, it seems to have worked because on all of my tests it has tripped in the appartement and not downstairs, having the type S ones by the meters also helps for any DC leakage currents.

You are both quite right regarding the bullying, initimidation and lieing.
If your meter is outside on the limit of your property they will do the Linky upgrade regardless of you following the "correct procedure" and writing all the letters in the world, they even broke the lock off the electricity sub station to install a Linky for the street lighting, it was a Passe EDF lock as well!!!!!
We'll see this month. It's scheduled for October. The subcontractors are going to have to have some hefty chain cutters in their van :D And therein lies the main reason for the refusal. We haven't been given a choice and judging by the bullyboy tactics employed, it certainly will end up costing more for the electricity. As we already pay TVA on the sneaky taxes piled onto the bill (OK, I know that is a government thing) I'll fight them in the trenches.....
Be alert.....your country needs lerts!
