    Abstract - (Show below) - (Hide below)

    This document is for synchronized phasor measurement systems in substations. It addresses synchronization of data-to-phasor conversions, data sampling, formats for timing input and phasor data output from a Phasor Measurement Unit (PMU). It does not specify response time, hardware, accuracy, software or a process for computing phasors.
