GreEner Tech: Sustainable Technology for Medium-Voltage Switchgear Systems

Abstract:
This paper presents the GreEner Tech project that aims to develop sustainable medium-voltage switchgear components, which are essential parts of the power distribution system. By focusing on resource-efficient materials and processes, the sustainability of these systems will be improved throughout and beyond the entire life cycle. This includes reducing electrical losses during operation as well as utilizing alternative materials that are recyclable and environmentally friendly. During the project a design methodology and a digital platform are developed, which enable the sustainable optimization of components in terms of design, materials, and processes - ensuring that the results can be transferred to various switchgear systems by defining transferable design criteria. In addition to this collaborative platform, comprehensive analyses and tests will be conducted to optimize electrical transmission properties and material durability. By combining these approaches, a medium-voltage switchgear component will be created that is not only environmentally friendly but also offers high electrical and cost efficiency yet maintaining reliability. This paper highlights key aspects such as sustainable design principles, systematic material and process selection, end-of-life strategies, sustainability assessment as well as the reduction of electrical losses, all aimed at maximizing resource conservation and enhancing the sustainability of medium-voltage switchgear.
