What is Phasor technology?
Phasor technology is considered to be one of the most important measurement technologies in the future of power systems due to its unique ability to sample analog voltage and current waveform data in synchronism with a GPS-clock and compute the corresponding 60 Hz phasor component (i.e. complex numbers representing the magnitude and phase angle of a 60 Hz sinusoidal waveform) from widely dispersed locations (see figure). This synchronized sampling process of the different waveforms provides a common reference for the phasor calculations at all the different locations.
