Abstract
An adaptive mimic filter-based algorithm for detecting the saturation of Current Transformers (CTs) has been presented and implemented in this paper. First, an adaptive method was developed for obtaining the line impedance of a digital mimic filter. The variations of the obtained line impedance were then used to detect the CT saturations. By using the proposed algorithm, the saturation period of a current waveform can be accurately detected. This paper finally utilized the MATLAB/ SIMULINK software and a DSP-based environment to verify the proposed algorithm. Test results show the proposed algorithm can accurately detect the CT saturations. ©2009 IEEE.
