SC – A3 Mission of the Study CommitteeThe mission of Study Committee A3 is to facilitate and promote the progress of engineering and the international exchange of information and knowledge in the field of high voltage equipment, and to add value to this information and knowledge by means of synthesizing state-of-the-art practices and developing recommendations.
SC – A3 Scope • Responsible for the theory, design, construction, and application of high voltage equipment components, equipment, and equipment systems for both AC and DC systems • Equipment: all devices for switching, interrupting, or limiting currents(CB, load/ disconnect/ earthing switches, FCL, etc.) independent of technology ( also includes surge arresters, capacitors, busbar and equipment insulators, instrument transformers, bushings, and all other high voltage equipment not specifically covered under another equipment study committee’s scopes ) • Emphasis is on function and interaction of high voltage equipment
SC – A3 Study Committee Membership • The SC currently consists of a Chairman (Mark Waldron, UK), a Secretary (E. Kynast, GE), 24 Regular Members and 11 Observer Members. • The 24 countries represented by Regular Members • ( Australia, Austria, Bosnia-Herzegovina, Brazil, Canada, China, Croatia, Czech, France, Germany, Greece, India, Italy, Japan, Korea, Norway, Poland, South Africa, Spain, Sweden, Switzerland, The Netherlands, United Kingdom and United States ) • The constituents of the SC come from Utilities, Manufacturers and Universities/Institutes.
