Presentation Synopsis

With The Average Age Of The 7f Family Of Units, In Both Simple And Cc Configurations, Now Approaching Or, In Some Cases, Exceeding 20 Years, Their Reliability Is Degrading. Generator Field Issues And Frequency Are Compounded By An Ongoing Increase In Starts/stops, An Issue That’s Been Covered Frequently At All User Forums For The Past Few Years. This Technical Presentation Will Highlight The Key Weaknesses, Driven By Age, Duty Or Original Design Deficiency (Or A Combination), And Attempt To Prepare Asset Owners For Planning And Maintenance. Some Key Areas Discussed Will Be Collector/brush Systems Maintenance/repair, Field End Winding Issues, Field Slot Component Problems (Including Component Migration, Insulation Delamination, Turn Shorts, Etc.), As Well As Rewinds. We Will Also Review How To Get These Items Addressed During Planned Outages, As Well As Discuss The Impacts If They Are Left To “Discovery” Or Unplanned Scenarios.
