Lessons Learned at AEP Transmission in Failure Prevention
Presented By: Carey Schneider American Electric Power TechCon 2019 Abstract Historically, utilities have used inspections and time-based maintenance to drive decisions on safety and failure prevention. The inspections and time-based maintenance still hold value, but AEP Transmission is also implementing real-time asset monitoring to provide more current and additional data points for failure decisions. AEP […]
