The Study Committee (SC) covers all aspects of rotating electrical machines associated with power generation and grid support ranging from research, development, design, manufacture, and testing of new machines to the commissioning, operation, condition assessment, maintenance, refurbishment, upgrades, life extension, conversion, storage, and de-commissioning of existing machines. Within these fields, SC A1 promotes the international exchange of information, knowledge, practice and experience, and adds value by synthesizing state-of-the-art practices to develop guidelines and recommendations.
