Operation of differential relay for power transformer using support vector machine

In this paper, the operation of differential relay for power transformer was presented using support vector machine. An SVM subroutine was used to discriminate internal faults from other situations, replacing the traditional Fourier method for harmonic restraint. The proposed methods was extensively tested and then compared to the traditional differential protection algorithm showing promising results. The application of the SVM tools is a new and important stage in the differential relay analysis methodology for power transformer protection.
