Elektro Gorenjska, a Slovenian electrodistribution company, wanted better insight into power grid parameters within transformer stations. They equipped over 260 of their stations with Iskra network analyzers, recorders, and power quality analyzers. These devices monitor electrical quantities and power quality in real time. Data is sent to Iskra's MiSmart software, which provides remote monitoring, alarm management, and reports. This new system allows Elektro Gorenjska to better maintain their grid and respond faster to failures or deviations.
