TN-S with and without Neutral conductors

Hello everyone,

What are the advantages/disadvantages of using TN-S system with and without Neutral conductors?. Where does it find its application?

  • You can even connect single-phase loads to a 3-wire system without N - just as long as they run at 400V (rather than 230V) - occasionally found in things like floodlighting and welders.

    Outside of 230/400V systems, you can have say 133/230V 3-phase systems and connect single-phase loads between two lines … much of the near continent used to favour such an approach for public supplies in the distant past.
