Testing and Calibration of Phasor Measurement Units (581.01 KB)

A Phasor Measurement Unit (PMU) is an electronic device that enables real-time computer control to protect the stability and reliability of a power grid. Using GPS-derived timing, the PMU synchronously captures voltage and current phase vectors to create SynchroPhasor data. Synchronous data from multiple PMUs are forwarded to a common point where analysis, control, and protection may be accomplished. Real-world application of PMUs has revealed a need for uniform performance across the various manufacturers of PMUs. Fluke Calibration, under a grant from NIST, is developing an automated system to execute and document PMU calibrations that conform to IEEE C37.118.1.
