“…Differential protection has been the main protection scheme in power transformers because of its simple principle and efficiency . When a power transformer is energized initially or experiences a sudden change in its terminals, a typically non-sinusoidal transient current flows in transformer windings which abruptly reaches a large value in the first half cycle [2].Although differential protection has been widely M.Afrasiabi, S.Afrasiabi, B.Parang, M.Mohammadi and H.Samet are with the School of Electrical and Computer Engineering, Shiraz University, Shiraz, Iran (e-mail: shpower77@yahoo, musa.afra@shirazu.ac.ir, benyamin.parang@shirazu.ac.ir, m.mohammadi@shirazu.ac.ir, samet@shirazu.ac.ir).…”

“…Several techniques based on artificial intelligence, digital signal processing, and probability theory and statistics have been developed in order to improve the efficiency of transformer differential protection schemes [8]- [11]. For instance, in [8] a method based on the Clarke transform and fuzzy logic to single out internal faults on power transformers is presented.…”

“…Research reported in [9] and [11] used high-order statistics and the second central moment techniques to distinguish between internal faults and energizations, respectively. Both methods presented good success rates in the event discrimination, but only [11] reported adjusts with no dependence of the transformer and system parameters. However, these methods did not consider transformer overexcitation, which is an important situation for validating new power transformer protections.…”
