      • Establishing Traceability of Synchrophasors at the National Laboratory Level
        Synchrophasors have emerged as a technology with the potential to improve grid stability via post-mortem failure analysis, and possibly predict insipient failures, allowing remedial action to be taken prior to a catastrophic event. But challenges remain before this technology can offer global solutions.
