Mechanical Dynamics & Analysis has analyzed and resolved generator stator bar abrasion events that have become common on some newer GE® Frame 7F and 324, 330, or 390 generators. The damage can cause ground faults leading to forced outages and complete stator rewinds. A principal cause of the abrasion is traceable to side ripple spring-induced […]

Over the past decade, there have been several reports of dusting on the GE® 7FH2 & 324 stator end-winding systems. The dusting has been found on earlier and late model generators. GE® 7FH2 and 324 type generators have a history of end-winding dusting as a result of materials used during manufacturing. A major contributor to […]
