And in this configuration, look what you get in Single-phase:




And here we have the 400V between 1 phase and neutral we were looking for !!


:?: 400v not between stage c is normal ?? 230 and phase to neutral :|

ok for the wrong interpretation of the graphic
but for the explanation of 400 between ph and neutral c is the right

in terms of other cretin Alain g : Evil:
more comments

Elsewhere no more comment on the three-phase since you are at the "top" and all the others only tell c ....

I 've not insulted, what's your job to pretend to know what you read on the web?

I will not start a fight with you my friend, I am in power since 26 years and I 've proved more me.

So you quarrel alone. 8)

J'vous have read diagonally, and I have just watched your Toff curves, sorry, fart xls file

Pdf doc says that it is a neutral displacement linked to the phases of load imbalance, and they give an example:


V3N can be calculated for the following impedances:
Z1 = R
Z2 2 = R
Z3 = 10R
.... Where V3N = 1,43Vn
Similarly, it determines V2N = 1,14Vn and V1N = 0,6Vn

voltage drop on one phase and overvoltage on another

If the phases were balanced, the problem does not exist
