Description
1. Real – world Case
In a large – scale power generation plant with steam turbines, the Bently 3500/22 – 01 – 01 – 00 was installed for continuous monitoring of turbine shaft vibration. One day, during normal operation, the system detected a gradual increase in the shaft vibration amplitude. The Bently 3500/22 – 01 – 01 – 00 immediately analyzed the vibration data and compared it with pre – set alarm thresholds.
As the vibration levels approached the warning limit, the system sent an early – stage alarm to the plant’s control room. Maintenance teams were alerted and began to investigate the issue. Through further analysis of the detailed vibration data provided by the Bently 3500/22 – 01 – 01 – 00, they discovered that a misalignment in the turbine coupling was the cause. Thanks to the early detection, the maintenance could be scheduled during a planned outage, preventing a potential catastrophic turbine failure that could have led to long – term power outages and significant financial losses.
