that, I'm not sure.

You have 2 entry points instead of one.

Well, I had only half a sequel then! : Lol: : Lol: : Lol: : Lol: : Lol: : Lol: : Lol: : Oops:

Exactly ! In sorting, you cut the circuit breaker in any case and you don't play dumb haphazardly!

Especially since all the electricians who do not respect the standards (or make a mistake on a connection) and the multiple works mean that the neutral is not necessarily the blue wire... moreover it was red a few decades ago ! : Mrgreen:

Probably a Belgian story then...
Because in France it is the earth (PE) that was red... a very long time ago...

Sorry yes it was the ground...sorry...but if the neutral is connected to the ground, it's the same...

For you frequency "shifter", then, maybe a 110V would have been more appropriate?

Christophe wrote:Three-phase 220 V = 3 phases at 127V with respect to earth or neutral (if connected to earth) = 127 * root of 3 between 2 phases = 3 * 220 V

Mono 220 V = 1 phase at 220V + 1 neutral

So I can wire my sorting with a mono in PNP or NPN (and variants) = 2 phases at 230 V with neutral between 2 pairs 0 on the 3rd pair...


Could you make a drawing, because I don't understand... the variants, is it PPN or PNN...? : Mrgreen:

Otherwise, in solar injection is it common for single-phase injections? The whole network is three-phase (with earthed neutral in the last transformers), phase balancing is important, how is it managed? From what PV power are three-phase inverters used? (Which, if smart, can help balance the phases.)

Yes ok I would do a diagram but I don't think it's necessary: ​​it's just the inputs of a 3-phase Tri circuit breaker.

First measurements of the oscilloscope on the network with the x10 probe in x1 mode (so the values ​​in Volt must be multiplied by 10):

And taaaadammmm!!!

Here is the curve of the pure sinus inverter...the sinusoid is perfect on this model! I do not believe it ! : Shock: : Shock: : Shock:

Is there a network sine and signal analysis specialist here...??? : Idea: : Idea: : Idea:

Attention, it is not the one that smoked which is much lighter and which is still awaiting repair...

For the drawing, I was kidding...

You just want to connect two circuits with a common point, nothing to do with the neutral.

But my question is serious. :)
