electrical dispersion

[mir]

so much for confirmation I ask you if it is better to carry, for a stretch of 50 meters, the current on average or in low voltage?

I think on average also because I need a smaller cable and I have fewer thermal dispersions.

thanks to any aid

50 meters is a microscopic distance. in low voltage it is almost definitely, unless you have very high currents. Remember that the medium voltage needs different protection infrastructures, it also needs to be transformed into low before use.

I understand, but perhaps I have neglected a significant figure. I have to bring 3 generators from 250 kw to the enel so I should bring 3 cables each down while only 3 for all on average.

No, I didn't understand what the system was like.
If you have an entire plant area on average, you certainly don't put a substation just to make a low-rise ride...

I have 3 low voltage generators and I have to go to the enel cab that wants the average voltage (current shield to the enel network).

each generator is from 250 kw to low voltage at a distance of 50 meters from the cabin.

I wonder if you should put the low->media transformer near the generators or if close to the enel cabin.

Sorry about the previous inaccuracy but I thought it was a simpler analysis.

Thank you.

Well, without any other information, it is best to put them near the generators, although for 50m really the difference is irresistible.
if then in those 50m there is for example a foundation on which you can walk, the cables on average must be buried, the ones in low can be channeled, with economic advantages, maintenance, etc.

I repeat, it is not an evaluation with few parameters.

consider then, that if you put the cabins near those of the enel, and you have a three-phase system without neutral, you can exploit a "cleaner" land because closer to the reference of land used by the enel. I don't know what your situation is.
