Hello everyone
I am in the process of carrying out a civil engineering guide plan for a mt / bt transformer station and I have a problem with the detail of the earth bar I do not know whether this one is correct or not. the neutral regime is TN
thank you in advance
Neutral scheme?
No idea, it's beyond my skills (at this level I only know the theory) but if someone has the answer I'm fine.
I thought that in TN mode there was only one earth connection, to which both the neutral and the masses of the devices were connected.
The advantage of this regime being that the quality of the earth connection does not influence the efficiency of the protection against indirect contacts.
Now I am amazed to see a specific earth connection for the neutral.

Take no risk and get the official text, possibly phone the electricity company!
