Powered by data: Availability and reliability for Chur’s low-voltage grid

Making grids smart doesn’t have to be expensive. IBC combines easy-to-integrate hardware and software. Over the next two years, transformer stations and distribution cabinets will be equipped with SENTRON 3NA6 COM NH fuses and SICAM EGS sensors. The Electrification X loT Suite turns secure grid data into KPI-based insights, enabling early peak-load detection, targeted countermeasures, and efficient investment planning.
Continuous monitoring and automated alarms boost reliability, reduce downtime, and improve maintenance efficiency for a reliable, future-ready, and cybersecure power supply.

A smart grid has nothing to hide

By 2040, the city of Chur in Switzerland aims to be climate-neutral. Today, around 88 percent of its electricity already comes from renewable sources. To tackle the remaining 12 percent, the local utility IBC Energie Wasser Chur relies on smart fuses, grid sensors and Electrification X to create full grid transparency and move the city one decisive step closer to its climate goal.
