Major Inspection of a 330H gas-turbine generator indicated that a stator rewind was needed. The unit failed electrical tests and had suffered with indications of heavy wedge slot and bar tie greasing.

Novosibirsk State Technical University (NTU) has developed an algorithm that helps protect synchronous generators from loop faults in the stator winding. The project was among the winners of the ...

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 ...
