Demo 4 objectives are addressed in three parallel sub-projects:
The first aims to research, analyze and model existing high-temperature low-sag (HTLS) conductors with a focus on ageing behaviour (temperature, electrical and mechanical effects) and determine the benefits of insulated cross-arms.
The second intends to validate all potentials for innovative design and field working processes, including retrofit process and live line working.
The third consists in the development of a prototype dynamic line rating (DLR) system based on low cost sensors allowing higher temperature operations of current line technologies.
The results will be packaged into a self-standing line upgrading package which will help TSOs to deliver overhead lines that are more:
The combination of the solutions enhances the existing system approach to AC overhead line repowering. It will also help TSOs and utilities to keep overhead lines reliable and resilient under the light of the developments in the European energy system, and allow replication by other ENTSO-E members.
