PMU measurements are often taken at 30 magnitude root mean square value and phase angle in polar observations per second (compared to one every 4 seconds form represents instantaneous electrical sinusoidal waveform. using conventional technology). Time stamping Phasor Measurement Unit (PMU) is a device that is used to each measurement to a common time reference (provided collect and provide instantaneous phasors from desire places by very high precision clocks) allows synchrophasors from of applications, attached with an instantaneous time and date of measuring called time-stamped data. Estimated phasors different locations and utilities to be synchronized. When sometimes are called synchrophasor, defined as a phasor that data from multiple PMUs are combined together, the is estimated from samples using a standard time as the information provides a precise and comprehensive view of reference for a measurement, and has common phase the entire interconnection. Synchrophasors enable a relationship as remote sites, is a synchrophasor.
