Generators are often downgraded units of scheduled service and maintenance. Experience reveals, however, that there is a distinct need for regular service of generators as well as close follow-ups on any developments in wear and tear on mechanical and electrical parts.
Pon Power has long experience in service on low-voltage and medium voltage generators. We conduct annual preventive maintenance and renovation according to supplier specifications.
Preventive maintenance includes:
- Inspection of rotor/stator windings
- Vibration measurements
- Inspection of diodes/varistors
- Status inspection in connection with insulation measurements
- Inspection/replacement of bearings
- Cleaning of windings
- Inspection/post-tensioning of cables
Renovation includes:
- Replacement of bearings
- Cleaning of stator and rotor
- Enamelling of stator and rotor (VI — VPI)
- Balancing of rotor
- Test of generator (depending on size and voltage level)
