The Service Continuity Guide handle all relevant topics during Maintenance, Repair, Extension (MRE) or on-site dielectric testing for GIS above 52 kV. It enhances the effective cooperation of users and manufacturers through 1) Definition and selection of MRE Codes, 2) Clear responsibilities, 3) Description of the main technical aspects including safety issues, 4) Recommendations for users and manufacturers and 5) Provision of use cases. It supports the use of IEC 62271-203:2022 Annex F.
