Activities The activities of CIGRE Study Committee D1 concern the monitoring and evaluation of: - Monitoring and evaluation of new and existing materials for electrotechnology, - Diagnostic techniques and related knowledge rules, - Emerging technologies with expected impact on the system medium to long term. Said activities are focused mainly on transmission and distribution but emerging generation technologies will also be specifically considered. Within this scope, the work of the Study Committee is principally scientific in nature and has as its main aim the provision of timely information on new developments and trends to other CIGRE Study Committees. In order to ensure that said work meets the expectations and requirements of its internal customers, the Study Committee will set up a suitable Customer Advisory Group responsible for establishing priorities, monitoring results and gauging internal customer satisfaction. Through its work the Study Committee strives to keep CIGRE fully aware of the evolution of materials and technologies relevant to its activities.
