Automated detection of cable defects in smart low voltage networks

Key Challenges and Goals

Low voltage network operators face unprecedented challenges due to the energy transition, including an increase in direct renewable energy feed-ins and growing network complexity. Intelligent sensor technology can help address these issues by enabling continuous monitoring of the power grid. One critical application is the automated detection of cable breaks and other line defects, especially in heavily meshed networks.

Detection and localization of leakages in water distribution networks

Key Challenges and Goals

Water losses occur in utility water distribution networks due to leaks in pipes. In some regions of Germany, these losses exceed 10%. It is essential to detect and localize leaks quickly to minimize water losses and reduce costs. They also drive significant financial losses—ranging from direct water treatment and leak detection costs to severe consequential damages caused by soil washouts. How can leaks be quickly detected and located to minimize water loss and reduce costs?

Data Enablement of the Grid Data Inventory in the Electricity Distribution Network

Key Challenges and Goals

At distribution system operators, a large portion of the network data inventory still often exists in the form of drawn schematics. These are often not spatially accurate and do not contain relationships between the objects. The goal of data enablement is to build a unified data inventory with object relationships, accurate spatial positioning, and electrically correct modeling, which can be migrated into a modern Geographic Information and Operational Management System (GIS).
