Phasor measurement units (PMUs) allow precise measurement of voltage and current phasors in power systems. A phasor represents a sinusoidal waveform using a unique complex number, containing magnitude and phase angle information. PMUs measure voltage and current waveforms and convert them to synchronized phasor representations, providing system operators visibility into the state of distributed locations across high-voltage transmission networks.
