What is Phasor Measurement Unit (PMU)

1.

PMU is a measurement device, developed in mid 1980s. It measures the electrical quantities such as voltage and current at node in the power system where it has been installed. It provides the real time phasor parameters of these quantities such as magnitude, frequency, phase angle and rate of change of frequency.

Has been defined by the IEEE as “a device that produces Synchronized Phasor, Frequency, and Rate of Change of Frequency (ROCOF) estimates from voltage and/or current signals and a time synchronizing signal”. A common time source (GPS) may be used for synchronization. The resulting measurement is known as a synchrophasor. Learn more in: PMU Phasor Estimation Using Different Techniques
