Industrial Automatic Control Systems and Controllers Annotation << Back Solid Shielded Insulation System: Guarantee of Smooth Operation under Harsh Environments and Reduced Internal Arcing Risk Jean-Marc Biasse, Venazio Ferraro, Gang-Jack Wang The reliability of medium voltage networks is crucial for the effective development of smart grids. The key role is assigned to medium-voltage switchgears, which must ensure the smooth operation in harsh environments and minimize internal arcing risk. The switchgears with Shielded and Solid Insulation System fully meet these requirements. Keywords: solid shielded insulation system (2SIS); harsh environments; medium voltage switchgears; internal arc.
