Mechanical Dynamics & Analysis performed a 7FH2 Partial Re-Stack of the core step iron & Full Stator Rewind on a GE® 7FH2 generator. Several 7FH2 units have experienced failures of the core step iron, ...
Historically, generator inspections require rotor removal (Figure 1). There’s a significant level of risk during this process due to possible generator damage during the disassembly, and it also ...
Large electrical generator stators are normally cooled by water. Unfortunately, generator availability is reduced when copper corrosion products plug the hollow strands of the stator-winding coil.
