Fast, automated, traceable calibrations that comply with IEEE C37.118.1a™-2014 and IEEE Synchrophasor Measurement Test Suite Specification-Version 2-2015
Today’s smart grid relies on phasor measurement units (PMUs) to deliver real-time, mission critical data on the voltage, current, frequency and phase within the distribution grid. To ensure consistent, accurate and credible PMU data, it is essential that PMUs be properly calibrated.
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.
Applications include calibrating PMUs before they are installed, and as required throughout their operational life; performing type tests of PMUs and other power grid tools; and performing first article approvals. Because the 6135A includes a three-phase 6135A Electrical Power Calibration Standard, you can also use it to calibrate wide workload of electrical power and power quality test instruments.
The integrated 6135A/PMUCAL system fully complies to the IEEE C37.118.1a-2014, IEEE Synchrophasor Measurement Test Suite Specification-Version 2-2015 and C37.242-2013 standards for PMU operation and verification. The system also fully complies to the 2016 draft standard IEC/ IEEE 60255-118 Ed.1. Because it is fully automated, even non-expert users can start using it quickly, performing a complete complement of required tests in just a few hours, as opposed to many days with manual techniques.
6135A/PMUCAL at a glance
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 electronically
