Fluke 6135A/PMUCAL Phasor Measurement Unit Calibration System

Features

The 6135A/PMUCAL Phasor Measurement Unit Calibration System is the only fully automated and traceable PMU calibration system available today. It is an ideal solution for PMU designers and manufacturers, as well as for national metrology institutes (NMIs). It’s also a perfect solution for third party calibration houses, electrical power utilities and organizations associated with electrical power transmission.

The 6135A/PMUCAL system enables you to:

  • Calibrate and test a PMU from a client PC, either at the site of the test system or remotely over the Internet
  • Quickly set up a PMU test
  • Speed through automated calibration procedures or interactively do custom PMU testing
  • Provide the required static and dynamic voltage and current conditions that occur in a power distribution grid specified by the standard
  • Apply those signals to a phasor measurement unit
  • Capture the PMU’s reported results
  • Evaluate the total vector error (TVE), frequency error (FE), and rate of change of frequency error (RFE)
  • Compare those results with the original stimulus
  • Evaluate against the thresholds defined in IEEE Std C37.118.1a™-2014
  • Create test reports, graphs and calibration certificates that can be readily printed or shared electronica
