Auf N fließen I1, I2, I3 - der Querschnitt bleibt gleich? Drehstrom ist überall / Unsymmetrische I

Why does the cross-section of the neutral conductor not have to be thicker than that of the outer conductor - after all, N carries all 3 currents? Realize that the three-phase system is (almost) everywhere. Determine the current on N with a phasor diagram. 00:00 overview 01:04 Three-phase systems everywhere 03:21 Cross section of the N. 03:35 Triple the cross-section? 05:14 omit N? Neutral point shift 06:00 Cross section of N as for L? 06:28 In with symmetrical load / vector diagram 09:52 In with asymmetrical load / vector diagram 11:47 In can't be bigger than the largest IL.
