GIS vs AIS - Life cycle assessment

Econonic and Environmentally FriendlyDiscussions About Environmental AspectsGoal and Scope of The Life Cycle AssessmentProcedures of The Life Cycle AssessmentResults of The Life Cycle AssessmentIn order to ensure the future supply of electricity we require sustainable concepts that preserve resources and do not harm our environment. Humankind needs a reliable and secure power supply that is also environmentally friendly and economic – today and in the future. On the one hand, the grids that are needed to transmit and distribute electricity comprise cables and transmission lines, and on the other, components such as transformers and switchgear. Designs (topology) of transmission and distribution grids vary depending on the application. For example, in the case of distribution grids we can make a distinction between utility grids and those of industrial customers. But it is also the available switchgear technologies that open up various possibilities for grid design. Thus, manufacturers and above all grid operators must find well-balanced solutions under a wide range of criteria. Synthetically produced sulphur hexafluoride (insulating gas gas) makes an important contribution to this ta...Get price
