Today’s LiveWire Spotlight examines a webinar conducted by NERC’s Failure Modes and Mechanisms Task Force providing the status of their efforts to identify and map the signatures of BES equipment failures.  They now have a collection of fourteen useful root cause flow diagrams available upon request – covering equipment types ranging from relays to breakers to power transformers.

During the December webinar, it was clear that the Task Force is prioritizing equipment failures resulting from BES resource evolution and severe weather events.  These are top-of-mind reliability concerns which could result in a costly fine if the findings are ignored.
