Detection and Classification of Internal Faults in Power Transformers using Tree based Classifiers [PDF]
IEEE International Conference on Power Electronics, Drives and Energy Systems, 2020 This article discriminates the internal faults from magnetizing inrush for a 3-phase transformer using a Decision Tree (DT). Afterwards, the internal faults are classified with DT, Random Forest (RF), and Gradient Boost (GB) classifiers. An array of time,

Identification of internal faults in indirect symmetrical phase shift transformers using ensemble learning [PDF]
IEEE International Symposium on Signal Processing and Information Technology, 2018 This paper proposes methods to identify 40 different types of internal faults in an Indirect Symmetrical Phase Shift Transformer (ISPST). The ISPST was modeled using Power System Computer Aided Design (PSCAD)/ Electromagnetic Transients including DC ...
