Operation principle

The Phasor Measurement Unit (PMU) features three main functional principles:
• To measure the power system related AC quantities (voltage, current) and to
calculate the phasor representation of these quantities.
• To synchronize the calculated phasors with the UTC by time-tagging, in order to
make synchrophasors (time is reference).
• To publish all phasor-related data by means of TCP/IP or UDP/IP, following the
standard IEEE C37.118 protocol.
The C37.118 standard imposes requirements on the devices and describes the
communication message structure and data. The PMU complies with all the standard
