What is neutral in a three phase system?
One more question, what you explained I understood perfectly ... do the three fuses take them out of service by disconnecting the cable that feeds those same three, right? There is currently a phase without light in the area and they are waiting for the Edesur gang to solve the problem.
If a phase is missing it may be over consumption. According to the problem that exists, they will cut the three phases a moment and then enable the three in sequence and quickly. This is because the three-phase equipment that could have been connected at the time of the cut begins to work normally. The problem is not always a fuse. It can be a joint. Many times while waiting for the crew, they have been searching for the fault for a while.
In my area, whenever we have cuts, it is only one phase, rarely the problem is at three o'clock (last summer we had a cut where the phases were cut in a period of three hours each, I do not know the problem). Also what I notice today, is that the majority of neighbors moved to the other phase, and then they come and fix the phase without service, and the other week the other is cut due to consumption, it is a problem. When you mention that "it can be a splice" do you mean that the crew must splice a molten or cut cable?
It should also be noted that if the phases change the three-phase motors could start in reverse. And you have to be very careful in those cases. Business blinds go down instead of going up (and one notices) but in an air conditioner it is more difficult to detect it and it can burn the equipment (just to give an example).
Facundo, the negligence of the neighbors is evident when changing phase, but at the same time EDESUR should not have competent employees, since they have (or should have) the elements to control the balancing of the phases.
The fuse holder connectors are the wires on both sides of the fuse so to speak. I heard about morcetos but I don't know where they are located. Whenever they come to fix it they do it in the block of the transformer. I repeat, thank you very much for the clear and precise answers and sorry for asking all at once.
