In this issue of The Synchrophasor Report, Isaac West, a power engineer, highlights a recent certification that distinguishes the SEL-2240 Axion as the first and only IEEE-certified phasor measurement unit (PMU) in the world.
For nearly two decades, SEL has maintained a keen focus on driving synchrophasor technology into the power industry. With the release of the first synchrophasor measurement-enabled protective relays in the early 2000s, SEL established itself as a leader in the PMU arena. Since the publication of the IEEE C37.118-2005 standard, SEL has continuously strived to comply with the latest synchrophasor standards. In 2013, SEL released the SEL-2245-4 AC Metering Module, a CT/PT metering module for the Axion that was the first SEL synchrophasor measurement technology to comply with the updated IEEE C37.118-2011 standard.

In 2015, IEEE invited SEL to participate in the IEEE Conformity Assessment Program (ICAP) for synchrophasors. The focus of this effort was to measure applicant PMU performance against the IEEE C37.118.1a-2014 standard for synchrophasor measurements. The Axion was SEL’s top choice for submission to ICAP.
On December 17, 2015, the SEL Axion was announced as the first PMU to meet the IEEE Standards Association (IEEE-SA) IEEE Synchrophasor Measurement Test Suite Specification—Version 2. To attain this certification, the Axion met or exceeded the rigorous requirements established by the IEEE Synchrophasor Conformity Assessment Steering Committee (SCASC), which consists of industry subject matter experts. Consumers Energy Laboratory Services, an IEEE-authorized independent laboratory, conducted the tests to verify compliance.
“Certification of the SEL-2240 Axion from a notable industry leader in power and energy, such as SEL, marks an important milestone for the IEEE Synchrophasor Certification program,” said Konstantinos Karachalios, managing director of IEEE-SA. “This program addresses a gap in the power industry by offering buyers of PMU technology a method to determine compliance of a product to the IEEE C37.118.1a standard before purchase and large-scale deployments.”
In addition to this recent certification, the Axion also includes several innovative features that make it SEL’s premier PMU:
