NEPLAN | Economic Cable Sizing and Thermal Analysis

back to overview

This calculation module checks all cables and overhead lines on their thermal capacity. Control is independent of the network structure (meshed, radial) and it requires the protection devices’ characteristics. The tripping time of protection devices is also considered. The calculation can be performed according to:

  • DIN VDE 0100 Part 540
  • DIN VDE 0103 or IEC 865-1:1993
  • ANSI



  • Worst fault location for thermal cable stress
  • Permissible thermal cable current according to standards and line input values
  • Permissible fault clearing time calculated

In case no protection devices are entered, the module can still calculate the maximum allowable fault clearing time.
