Hello,
novice of all kinds in the field of energy saving but strongly interested in applying certain precepts home, I heard a few times ago a system to install directly on the EDF meter inside the house and that would limit overvoltages and over-consumption of electricity in the home.
Only here, I had this information on a piece of newspaper OuestFrance 3-4 months ago and that presented the trick as a legal limit and therefore the company that produced it could not guarantee its installation. My questions are as follows:
- Did any of you hear about this process?
- Under which denomination?
- How efficiently? (mainly savings)
- What cost?
- What legislation?
Thank you for your answers. Best regards.

In principle it works. It is called "linearizing" (I believe) the voltage (a device supplied with 240 V will consume more than 230V or 220V) besides one can wonder pkoi one went from 220 to 230V a few years ago. ..
And peak voltage can damage your home appliances faster.
In practice it is less obvious: it is the principle of an online UPS and an inverter online 2kW it costs 1500 € ...
So the box less than 200 € which manages a power of 3kW and more, I have doubts about its reliability and real efficiency ... moreover it necessarily has internal losses.
Question legality and homologation: I do not know but if it is not careful in case of problem ...

Hello
Well, it does not work like that!
p = ui cos phi
if u lower i is higher but p remains constant
Well, it is to pass more current without increasing the section of the cable and to limit the losses joules
a device powered by 240 V will consume more than 230V or 220V)

besides, we can wonder pkoi we went from 220 to 230V a few years ago ...

a) Of course, if it works, how is it ... for the resistive element it is systematic: the more you have tension, the more power you have!
So an electric heater powered by 230 V will consume more than a radiator in 220 V but it will also be more power. Same with the bulbs and any other pure resistive system !!
I'm not going to give you a lecture on Ohm's law ...
The cos phi = 1 for pure resistive.
But the resistive = 80% of our consumptions ... (at least)
b) For your explanation of the losses joules I do not believe (figures here: http://www.volta-electricite.info/artic ... =fr&pg=605 that's more than enough) especially for the reason given in a) so there's probably another explanation ...

as for courses you will iron!
ok go we start the course u = ri so i = u / r
r being a constant (even if it is not the case because rt = ro (1 + at))
if u weaker then i stronger
and as p = ui then
ditto in power
by having a network bt in 400volts and as no transformer has been changed one is going from 20 000 in medium voltage to 22 000 volts
and for high voltage the gap is even greater
over thousands of km of line the economy made at the level of joules losses is huge
in addition to the places of modif the network to pass more power one remains on the same threads and the economy is COLOSSAL
