Abstract	This study proposes an effective symmetrical fault detection technique during power swing in distance relaying using phase-space (PS) method. This is based on an embedding theorem which shows that a time series can be mapped to a higher-dimensional space called PS through embedding. Thus, a sampled signal can be transformed into the PS so that its features can be more clearly viewed. The process starts at retrieving the current signal samples and process through PS, the original signal is decoupled into two parts such as power swing and symmetrical fault part. The symmetrical fault detection during power swing is easily achieved as the symmetrical fault part of the signal produces an irregular shape compared with the shape produced during from the power swing condition. The symmetrical fault detection signal using PS (FDPS) detects the symmetrical fault during power swing in the transmission line with wide variations in operating conditions and the results from extensive studies indicate that the proposed FDPS can reliably detect the faults during power swing.
