Designing, drawing, calculating and monitoring low-voltage installations in accordance with the HD384

GE is launching the new ProceraPlus® software package for designing and calculating complete low-voltage installations. ProceraPlus® is a Windows-based package,which enables the user to choose the correct security for the most appropriate distribution system, as well as related components. ProceraPlus helps to quickly and simply calculate the short-circuit resistance in each point of the installation. The program offers a perfect balance between installation costs and comfort level (preventing unwanted cuts).

ProceraPlus® can make calculations for up to 50 distribution boards, 300 circuits and maximum 6300 A. New elements in this version include:

  • The option to install 6 ordinary and 1 emergency source in parallel.
  • Multiple predefined end circuits such as sockets, lighting, heating, capacitor bank, engine or LV/LV transformer.


Concept of the installation

  • In horizontal and vertical direction


  • Number of supply sources: 6 ordinary + 1 emergency (up to 6300A) in parallel + standby power unit
  • Earthing system: TN(-C-S), TT and IT with and without neutral
  • Public distribution starting from Ik


  • Distribution board
  • Terminal circuit: Motor, socket-outlet, lighting, heating, transformer LV/LV, capacitor bank (pro distribution board), miscellaneous.


  • Circuit breakers for general purpose
  • Residual current devices
  • Safety fuses of type gG/gL, type aM + thermal engine protection
  • Back-up protection and selectivity


  • Dossier = collection of documents
  • Document: cover page, sources, single-wire diagram (general, pro distribution board), circuit (+ characteristics), cable table, security device setting
