Physics-Informed Dynamic State Estimation for Current Transformers Using Graph Neural Networks

Michael A. Boateng, Gabriel Gauderman, Nathalie Uwamahoro

Current transformers are fundamental to power system protection and measurement, yet transient core saturation can severely distort the secondary current and degrade measurement accuracy. Existing dynamic state estimation methods rely mainly on numerical discretisation and iterat…Read more
