Controlled switching strategies for transformer inrush current reduction: A comparative study
(Elsevier, 2017-04)
Transformer inrush current can be efficiently mitigated by controlled switching. For energization of three-phase transformers, several strategies have been developed that depend on whether the residual flux can be measured ...

Parameter estimation for hot-spot thermal model of power transformers using unscented Kalman filters
(IEEE, 2023)
This paper presents a parameter estimation technique for the hot-spot thermal model of power transformers. The proposed technique is based on the unscented formulation of the Kalman filter, jointly considering the state ...
