Superconducting Fault Current Limiter
Growing electricity demand, the expansion of renewable power and progressive power grid meshing face operators of electric grids with a new challenge: Higher loads, more distributed generation, and changing load flows in the networks lead to increasing fault currents in the event of short circuits. This trend will require substantial spending for replacements of transformers and switchgear in stretched sections of the power distribution infrastructure where fault current levels threaten to exceed the rating of operating equipment in place. The Superconducting Fault Current Limiter (SFCL) launched by Nexans is a fundamentally new self-acting system that protects grid operating equipment from damaging current peaks during faults events and circuit feedbacks. The SFCL can be deployed to facilitate grid expansion and avert ahead-of-schedule upgrading. It also enables cost-efficient grid stabilization and optimization.
