Today’s LiveWire Spotlight evaluates three NERC Lessons Learned where Fault analysis was used to assess the operating condition of a Transmission and/or Protection System either before, during, or after an electrical event. All three offer recommendations regarding training, tool upgrades, maintenance preparation, and troubleshooting that aim to make Fault analysis a seamless part of a reliability program
Electric system outages that result from, or are extended by, inadequate Fault analysis continue to be one of NERC’s top reliability concerns. New reliability requirements could result if these Lessons Learned do not reduce the incidence of these types of threats.
