Activities SCB2 is composed of 7 Advisory groups and 22 WG, JWG and Task Forces. The Strategic, Customer and Publication Advisory groups have in charge to Advise SC Chairman as far as Strategy, Customer satisfaction and publications are concerned 4 Technical Advisory groups provide advice for assisting the Chairman in the definition of the directions to be followed by the SC. Their responsibilities are : 1.to coordinate WG within the scope of theTechnical AG ; 2. to identify future direction of the technology in the technical area. 3. to prepare new items of work and to submit them to CAG and SC Chairman 4. to coordinate TUTORIALS between different WG ; 5. to attract new Members and retain existing members. The list of WG is following : JTFB2/D2.18 : Overhead Lines Geographical and Asset Information System JWGB2/B4/C1.17 : Impacts of HVDC Lines on Economics of HVDC Projects JWGB2/C1.19 : Increasing Capacity of Overhead Lines - Needs and Solutions TFB2.20 : Management of risks due to load-flow capacity increases in Transmission Overhead Lines WGB2.08 : Transmission Line Structures WGB2.16 : Meteorology for overhead lines WGB2.21 : Arc protection and diagnosis for composite string insulators" WGB2.22 : Mechanical security of overhead lines with effective failure containment measures : design loading cases and strategies for effective anti-cascading supports WGB2.23 : Geotechnical and structural design of the foundations of HV & UHV Lines, application to the updating to the refurbishment and upgrading guide WGB2.25 : Preparatory studies on specifications for revision of IEC testing of Self Damping and conductor fatigue characteristics (new IEC Spec.), for high temperature Fittings (IEC 61284), for tests on spacers (IEC 61854) and on dampers (IEC 61897) WGB2.26 : A Guide to Evaluating and Accepting New Types of Overhead Conductor including those running at high temperature.
