Frédéric Dillemann Schneider Electric More integrated substation , an opportunity for IEC type solution users Frédéric Dillemann Schneider Electric

Minimising the change in operating habits Padmonted solutions : major changes in operating habits Hotsticks manoeuvres Complete change of operating processes Non- homogeneous operating modes with the existing IEC installation Need for training ( more “sensitive solution “)  Our suggestion : More integrated substation should include “key components ” in conformity with IEC operating habits

Keeping the same level of safety Padmonted solutions : No internal arc withstand Questionable safety MV switching failure : explosion with inflamed oil in presence of the operator and risk for the public Isolating failure : explosion ; danger for the public  Our suggestion : Each function of the substation should warranty the adaquate level of safety . MV swichgears should have internal arc withstand
