Detection of Open Circuiting of Secondary Winding of Current Transformer Using Combined Feature of Hilbert Transform and Stockwell Transform

This paper presents a technique based on combined application of the Hilbert Transform and Stockwell Transform for the detection of open circuiting of secondary winding of the current transformer. The proposed algorithm has been tested in the presence of the resistive inductive as well as capacitive loads. The proposed study is performed in MATLAB/Simulink environment. The simulation results show effectiveness of the proposed algorithm for detection of open circuiting of the secondary winding of the current transformer core.
