The document provides guidance for synchronization, calibration, testing, and installation of phasor measurement units (PMUs) applied in power system protection and control. The following are addressed in this guide: a) Considerations for the installation of PMU devices based on application requirements and typical bus configurations. b) Techniques focusing on the overall accuracy and availability of the time synchronization system. c) Test and calibration procedures for PMUs for laboratory and field applications. d) Communications testing for connecting PMUs to other devices including Phasor Data Concentrators (PDCs). This guide is intended to be used by power system protection professionals for PMU installation and covers the requirements for synchronization of field devices and connection to other devices including PDCs. New IEEE Standard - Superseded. Guidance for synchronization, calibration, testing, and installation of phasor measurement units (PMUs) applied in power systems is provided.
