Compliance Table Electrical Three Phase Not Balanced! Linky jumping!
Compliance Table Electrical Three Phase Not Balanced! Linky jumping!
Hello,
I am an Electrician by training and a Technician for a big company.
Having made the purchase of an old house (1940) This one has an installation
Electric three-phase (small engine sump in cellar, serving only very rarely)
The secondary tables ground floor, 1er and second have been redone about 8ans. (Not cut neutral)
I intend to restore the main table (wood) cellar which is really collector ds at first.
Also when I use machine washed, tumble dryer and electric oven my limky counter cut me the installation.
So I realized that I had to balance my three-phase installation. (I noticed the imbalance with the limky counter
which allows me to have the power in real time)
Written: 12 KW, hence 4000VA per phase.
Being a little lost, To know if I have to go back in Single phase with EDF (500 euros connection fee) and replacement of the table.
Or balance my three-phase installation by replacing the main board anyway (higher cost for a three-phase switchboard)
Thank you in advance for your advice.

Personally I would not hesitate a second, even if it must cost 500 €! Rebalancing, in addition to the very old, it can be quickly a galley, or even be impossible (except to break everything).
And with a little luck and a little personal "discipline" on using large consumers at the same time, you might be able to upgrade to 9kVA instead of 12, which is about $ 20 / year in savings. Little consolation, certainly, but consolation all the same!
Good luck.

If the cables leave a meter (or even several) it is necessary to act, provided they have a sufficient section there will be nothing to break ...
Otherwise you can also move if possible some energy-consuming devices on another circuit ... which to make a derivation between 2 taken ... must break a little but not everything!

Roughly speaking it is 7-8 kW of cumulated power if it is on a phase is 30-35 A ... it exceeds largely 4000 VA per phase ...
You have to see the tolerances of disequilibrium tolerated by Linky, I deduce that you have a three-phase linky?
The price of three-phase subscriptions is probably higher than in mono ...
Switching from three-phase to single-phase is just to remove 2 phases and change meters (although a three-phase can count only one of the 3 phases ...)!
The opposite is much more complicated (EDF will certainly ask rather 5000 € than 500 € in this case).
You are in sorting with neutral regime so 3 phases of 230 V + N? That's it?
I'm asking because in Belgium, for example, there are 3 phases of 127 V without N ... so 230 V between phases.
In short the interest of switching to mono would be just to avoid the linky jumps to see if the imbalance is configurable by software and make a simulation with subscriptions and different costs ...

Re: Compliance Table Electrical Three Phase Not Balanced! Linky jumping!
At home, I had sort and mono. The breaker was very sensitive. An electrician told me that the three-phase requires an electrical installation and an impeccable earth, which was obviously not the case. I deleted the three phase and since then no more problems.

Did you have three-phase linky too?

No no. But Linky is coming soon, I got the notice. No way to escape.

Re: Compliance Table Electrical Three Phase Not Balanced! Linky jumping!
Thank you all for the advice.
Yes I'm good sorting with neutral system so 3 phases of 230 V + Neutral.
(230V between a phase and neutral and 400V between phases)
during my new contract with EDF the subscription tri has the same price when mono.
I thought also increased the P. counter to 18KVA with a monthly cost of 12 € per month?
I would switch to 6000VA per phase against 4000 VA currently, so more comfort for
to balance my three-phase installation?
When do you think ?

What seems to be the first goal, right?
PS: by the way and from my own experience twenty years ago in a house of the same age, the transition to mono, related to a complete overhaul of the electrical system in the street by EDF (air passage underground) , allowed me to go from 12 to 9 kVA without any worries.

Re: Compliance Table Electrical Three Phase Not Balanced! Linky jumping!
Hello,
I am surprised that a table redone 8 years ago have no break of neutral ... not by a professional I guess?
If the tables are well marked, allocating large consumers should not be difficult.
Electric heating ? equipotential earth?
Apparently it's the oven that has nothing to do on the same phase. It must be separate on an 32 A circuit?when i use machine washed, tumble dryer and electric oven my limky counter cut me the installation.
