What is the mission of SC C4: SC C4 deals with methods and tools for analysis related to power systems, with particular reference to dynamic and transient conditions and to the interaction between the power system and its apparatus/subsystems, between the power system and external causes of stress and between the power system and other installations. Specific issues related to the design and manufacturing of components and apparatus are not in the scopes of SC C4, as well as those specifically related to planning and operation and control, apart from those cases in which component/apparatus/subsystem behavior depends on, or significantly interacts with, the performance of the nearby power system. The fields on which the activity is carried out are: Power Quality Electromagnetic Compatibility/Electromagnetic Interference (EMC/EMI) Insulation coordination Lightning Advanced Tools for the analysis of power system Performance Power systems dynamic performance models and analysis
