99% aller Haushaltsdrehstromanschlüsse in Deutschland sind 3*400V/220V 50Hz, also ein sternförmiges Netz. Daneben gibt es (in BRD sehr,sehr selten) ein 3~230V Drehstromnetz in Dreieckschaltung, also Ich rate dringend, diese Schaltungsart des Herdes nur zu wählen, wenn du ganz, following on my induction hob post, I d be interested in just understanding quite what the above means. The hob as mentioned has yellow/green,blue,brown and black, with both black and brown being L1 and L2. So why have two lives.. whats the advantage, and whereby 400v ?

On the continent, sometimes cookers are wired to two separate phases - two independant supplies. R Joined14 Sep 2006Messages6,343Reaction score385LocationGloucestershireCountry

Oh, go on, I'll "split" the difference... T Joined21 Sep 2006Messages309Reaction score8Country
The phasor spacing is 120 degrees between each phase for a three phase system. If you just use tow phases, how does this relationship change to 180 degrees - please explain as I genuinely do not understand this. G Joined9 Nov 2006Messages7Reaction score0Country
the chart on the 3 phase sine waves on wikepedia helped me a bit. S Joined30 Apr 2006Messages224Reaction score0Country

Only if your DNO provide you with 'split phase' (460v phase->phase) [I believe its often used in rural situations for domestic setups (service drops might be long, etc) with storage heaters, provides an econonomial way of distrubuting the current over single phase where no big motors are going to be used - but I'm willing to be corrected on that] B
As far as I am aware, spliting phases by a DNO is illegal in the UK, can't comment on Europe. They generally split the 3 phase supply to provide two phases, and simply do the same elswhere so that the overall supply is balanced.
