ABB Air Gap Inspector can be used during planned outages without removing the rotor, and in cases where removal of the rotor is not possible. The inspections enhance preventive maintenance work, including ABB preventive maintenance level L3 and ABB AbilityTM LEAP (ABB Life Expectancy Analysis Program).
In-situ visual inspections can be used for:
- Internal inspections during minor outages
- Inspections in combination with ABB preventive maintenance level L3 and, to some extent, L4 (in special cases when rotor removal is not possible)
- Gathering additional information to support ABB AbilityTM LEAP
