Competence, Experience and Integrity
Maintaining and repairing 20th Century generators with 21st Century insights and abilities starts with pulling together the right expertise.
Process and Procedure
A complete and comprehensive mechanical, electrical, and visual inspection is performed on every generator stator and rotor prior to dis-assembly.
Hydro Generators – Stators
- Stator Rewinds, Half-Bars, and Diamond Coils
- Core Restacks, Partial and Complete
- Testing and Inspecting
- Main and Neutral Interchanges
- Rewedge and Tighten End Windings
- Through-Bolt Retightening and Replacement
- Coil Splicing
- Corona Repairs
Turbo Generators – Stators
- Rewinds (Conventional, Gas, or Water-Cooled)
- Core Restacks and Repairs, Partial or Complete
- Re-Wedge and Tighten End Windings
- Through-Bolt Re-Tightening and Replacement
- Partial and Full Restacks
Hydro Generators – Rotors
- Rotor Winding
- Testing and Inspecting
- Field Pole Removal and Replacement
Turbo Generators – Rotors
- Rewinds, Testing, Retaining Rings Removal, etc.
- Testing and Inspection
Adding Value
At every step within each procedure, Action Technology seeks ways to extend the life of a generator by reducing even the small outage risks.
Action Technology understands modernization and life extension of the generator is the job – not simply repairing and maintaining. Action Technology is skilled in problem-solving through innovative solutions. Whatever the issue on a generator (adequate design, a flaw in manufacturing, loose windings, thermal aging, load cycling, partial discharges, contamination, questionable test results, or something else) Action Technology has people ready to help develop a path forward. Every Action Technology crew member understands the reasoning behind the careful, detailed rewind management and methodology that assures a smooth-running generator.
