Fluke Calibration 6135A/PMUCAL Phasor Measurement Unit Calibration System

Smart grids rely on phasor measurement units (PMUs) to deliver real-time, mission-critical data on the voltage, current, frequency and phase within the distribution smart grid. For the smart grid system to work reliably, PMUs must be calibrated.

The Fluke Calibration 6135A/PMUCAL Phasor Measurement Unit Calibration System is claimed to be the only automated and traceable PMU calibration system available. It is suitable for PMU designers and manufacturers, national metrology institutes, third-party calibration houses and electrical utilities.

The product is an integrated system of six components that completes the approximately 600 tests that certify a PMU configuration meets the latest performance standards of the IEEE Standard for Synchrophasor Measurements for Power Systems (IEEE C37.118.1:2011 and IEEE C37.242). The system completes the tests in 6-12 h versus 2-6 weeks with manual test methods. Because it’s an automated system, even non-experts can start using it quickly to perform a complete complement of required tests.

The system, which is mounted in a 19″ rack with an integrated test connection panel, includes a server PC, GPS receiver, system timing unit and three-phase 6135A Electrical Power Standard. It also includes calibration software that lets users create and store personality profiles for the PMUs tested frequently, as well as run full certification tests and a wide range of automated and interactive tests.

The test system architecture lets a user-provided client PC access the test system over the internet from anywhere in the world. System accuracy yields a test accuracy ratio of 10:1 against the 118.1 PMU specifications.
