"Low voltage network planning". Click here for the overview.

Plants are often designed without paying particular attention to selectivity. In the end, this often has no consequences, as there is no fundamental obligation to set up a selective network. In the regulations, this requirement is specified for certain building areas or parts of the plant or it is required by the customer on a flat-rate basis. However, one thing these systems have in common is that the selective net design is not already implemented in the planning, or that an optimization of the system after it has been built is almost impossible, or only possible with large-scale conversion measures, corresponding costs and disruptions in the operating process.


This course teaches the basics of selective network design and the connections between selectivity and back-up protection and shows how to integrate the topic already in the planning phase.



  • Selectivity requirements and regulation standards

  • Current discrimination

  • Time discrimination

  • Full and partial discrimination

  • problems of cross-manufacturer selectivity

  • Benefits of back up protection

  • Advantage of modern low voltage protection devices with direction detection



  • None


We are looking forward to meeting you in the event!
