Abstract
The paper is dedicated to analyzing the use of Kalman filtering theory for Application in digital differential protection relay of power transformers. The state variables for the fault identification and protection operation criteria are described. Comparison of operation times of differential protections, based on Kalman filtering theory and Fourier algorithm is presented.
