NEPLAN | Fault Finding

back to overview

This module allows the detection of faults in electrical networks. Fault Finding addresses essentially faults in normal networks and in resonance earthed networks (the measured distance related to the total ring length or the total ring reactance).

General Characteristics

  • Detection of fault location or faulted elements based on measured phase currents, phase voltages or reactances
  • Measured values are entered in the protection devices or imported
  • Detection of all nodes in a certain range of tolerance defined by the user
  • Calculation is independent of the network structure and voltage level for short circuit


After the calculation, the module will display the following results:

  • Faulted element . It will also be displayed on the single line diagram
  • Fault distance
  • Nodes between which the fault was located
  • Nodes within the faulted area defined by the range of the tolerance
