Synchro-Lissajous (Synchronized Lissajous Curves)The video above shows a synchronized Lissajous curve for a high impedance fault on a distribution feeder that is seen by two WMUs: (a)-(b) voltage and current waveform measurements from WMU 1 that is installed at the beginning of the feeder; (c)-(d) voltage and current waveform measurements from WMU 2 that is installed at the end of the feeder; (e) the corresponding synchronized Lissajous curve. Each time step in the video is 56 microseconds in real time.
