GE’s DIRIS and TurboRotoscan inspection systems will be used in 19 generators manufactured by GE, Alstom, Mitsubishi and Brush at seven of Alinta Energy’s gas-fired power plants. The systems will alert the utility to potential generator issues and give it time to evaluate its options. Inspections will begin in April 2016 and be performed through 2020.
The DIRIS robot will give Alinta Energy modern robotic instrumentation and tooling to allow fast and reliable remote inspection of the turbogenerator. It performs critical tests of the generator stator iron core laminations, stator radial wedging system and conducting a visual inspection of the inside surfaces of the rotor and stator.
The TurboRotoscan system will perform inspections of the generator retaining rings while the rotor remains in place and while the retaining rings are mounted on the rotor.
