In a smart city, the importance of electricity is amplified and constantly increasing, and even short power cuts are more damaging. For the local utility, Helen, the new district brings about the need to introduce smart and reliability-improving solutions for electricity distribution.
In city networks it is crucial that faults are located quickly and accurately to avoid costly power outages.
To meet the high demands the smart city district is putting on electricity distribution, ABB's innovative medium-voltage switchgear solution UniGear Digital.
-Fast and precise actions in case of network failures possible with the permanent active supervision feature of IEC 61850 digital communication.
- Improved reliability and functionality of the power system with IEC 61850-9-2 sampled values (process bus), which is used for distribution of voltage measurements.
- Accurate measurements and easy data management in the power system thanks to sensor technology.
- Reduced cost and minimized footprint as no separate voltage transformer measuring bays are needed.
