Brukergruppen for kraft- og industritransformatorer
CIGRÉ
CIGRÉ er en organisasjon som utarbeider rapporter for høyspenningsanlegg basert på erfaringer i bransjen. Organisasjonen er basert på frivillighet og fungerer som en brobygger mellom forskning og anvendelse.
Cigre studiekomite A2 – Power transformers and reactors består for tiden av 28 regulære medlemsland og 16 "Observer" medlemsland. Frode Johnsen, Statnett er norsk medlem i Cigres studiekomite A2 - Transformers. På denne fanen legges fortløpende ut informasjon om pågående arbeid for studiekomite A2 - Transformers.
Frode Johnsens maksimale tidsperiode som norsk medlem i Cigres studiekomite A2 utgår i 2022. Det bes om at akuelle kandidater til nytt norsk medlem i SC A2 tar kontakt med Brukergruppen eller melder dette til Den norske comite for CIGRE (Generalsekretær Bjørnar Brattbakk).

Cigre konferanse SC A2 (sammen med SC B3) Bucuresti, 9-11.10.2021:
Preferential subjects of SCA2 and SC B3 colloquium:
PS1: Integration of intelligence on T&D Substations
Expectation and benefit from digital substation and digital transformer
Digitalisation into T&D assets: application of Internet of things (Iot), Digital twin, Light Detection and Ranging (LIDAR), Geographic Information System (GIS), Artificial Intelligence (AI), use of robots and drones, etc.
PS2: Reliability T&D equipment and substations in the future:
Impacts of Distributed Energy Resources connection on substations: improvements of thermal performance, aging impacts, Probabilistic of Failure (PoF), transformers dynamic loading profiles
Design, test, insulation, monitoring, maintenance of step-up, secondary substation and DC converter transformers,
Design and operational requirements for future applications: wind and photovoltaic.
PS 2: BEYOND THE MINERAL OIL-IMMERSED TRANSFORMERS AND REACTORS
Alternative technologies for improved safety and environmental performance: gas-insulated, ester-immersed, dry-type and solid-state transformers,
Operational experience with transformers using these new technologies,
Advantages and limitations, impact on specifications, high temperature applications, business cases.
PS 3: BEST PRACTICES IN TRANSFORMERS AND REACTORS PROCUREMENT
Return of experience: factory qualification, design reviews, implementation of new specifications, on-site vs virtual witnessing,
Quality control and testing: manufacturing check points, sub-supplier qualification, validity period for type tests, enhancements to standards, special tests, short-circuit test, paper DP measurement,
Dealing with non-conformities, performance guarantees, warranty
