Identification of transformer internal faults by using an RBF network based on dynamical principle component analysis
Ozgonenel, Okan; Kilic, Erdal; Thomas, David; Ozdemir, Ali Ekber (Ieee, 2007)In this paper; a method is proposed to detect and identify parameter faults in nonlinear dynamical systems. The approach is based on the principal component analysis (PCA) and artificial neural networks (ANNs) based on ... -
Modeling and simulation of 2.5 MVA SF6-gas insulated transformer
Ozgonenel, Okan; Thomas, David (Tubitak Scientific & Technical Research Council Turkey, 2017)In recent years, environmental awareness has been a great concern, and even governments have sometimes been under pressure to comply with bilateral agreements. Mineral oil/epoxy cast resins are one of the most harmful soil ... -
PCA based protection algorithm for transformer internal faults
Kilic, Erdal; Ozgonenel, Okan; Usta, Oemer; Thomas, David (Tubitak Scientific & Technical Research Council Turkey, 2009)In this paper a new protection scheme is introduced to detect and identify transformer winding faults. The new approach is based on artificial neural networks (ANNs) using radial basis functions (RBFs) and the principal ... -
SF6 gas-insulated 50-kVA distribution transformer design
Ozgonenel, Okan; Thomas, David; Kurt, Unal (Tubitak Scientific & Technical Research Council Turkey, 2018)There are increasing environmental concerns such that governments are pressured to cooperate with international concurrences. One of the most harmful contaminants is mineral oil when it infiltrates the soil. Although it ...
