Papers regarding all aspects of power, special, distribution and instrument transformers are encouraged. Papers will be divided in three sessions listed below.
- Modeling and Simulation
Numerical modeling in design, multi-physics and coupled problems
Transients, harmonics, lumped and distributed parameter models
Machine learning and hybrid models, models for digital twins - Materials, Components and New Technologies
Transformer components, insulating and magnetic materials
New concepts and technologies in the transformer industry
Digitalization and smart grid applications - Transformer Life Management
Monitoring, diagnostics and condition assessment
In-service experiences and case studies
Environmental aspects and resilience
As this is a joint event, papers belonging to CIGRE SC A2 colloquium preferential subject will be presented jointly in the sessions where they fit best with a clear mark of the preferential subject.
