Main goal of this study was to indicate which equipment and in which period will not be able to withstand reached values of the short circuit currents. Equipment was checked against values of the short circuit currents for 2011, 2015 and 2020.

Breakers, switches and current transformers were checked for the following substations:

  • SS Niksic
  • SS Podgorica 1
  • SS Bar
  • SS Berane
  • SS Mojkovac
  • SS Pljevlja 1
  • SS Tivat.

Short circuit calculation was performed for three-phase and line to ground faults.

Type of services provided:

  • Equipment data acquisition and classification;
  • Short circuit calculation;
  • Equipment check against values of the short circuit currents;
  • Suggestions for а possible equipment replacement.
