neutral lack of electrical service in the house
Hello, I did not know that distribution, in my list there were: 3 phases + neutral (with access to the phase and line voltages), and that of 3 "lines", as was the old CADE in a part of the Federal Capital in Argentina 3 x 220 V (without neutral) (something that surprised me the first time I stumbled, and that I did not know of its existence because I tried with the polisher and turned on both!)
bandurri the vast majority of western countries work with 2 phases and a neutral or only MONOFASICO, that is to say a single phase and a neutral, in the industrial AREA in the HUGE MAJOR COUNTRY it is used in the INDUSTRIAL area 3 phases and one neutral as normal general, so in a few countries I estimate 2% skip the rules and from what I see Argentina-Chile-Uruguay use another valid style of connecting their residential and industrial facilities that I see as a technician or engineer makes "INCOHERENT" but of course that bothers more than one here apparently ..........
You have to start from the generation, which is always three-phase, so a three-phase distribution, and as balanced as possible, is the best option to extract the greatest power to the generator.
The same happens if the power is extracted from an MT / BT transformer, the three-phase distribution (in its 2 versions 3 F + N or 3 Phases only, as we discussed with elektomaq) produces the highest transfer efficiency. In Argentina, in many districts 3 F + N is already lowered to the houses, which results in a much more balanced load, and if you have to use engines, they behave much better.
Totally agree with Axel Stone, and I support what Bandurria comments, regarding the behavior of electricity. Hopefully the friend leo87, get this and do not fall into confusion, 220v systems. single phase
