More integrated substation , an opportunity for IEC type solution users

2. 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

3. 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
