What is overspeed effect on turbine?

The overspeed effect on a turbine occurs when the rotational speed exceeds the designed operational limits, potentially leading to mechanical failure. This can cause excessive stress on turbine components, resulting in vibration, overheating, and possible catastrophic damage such as blade fractures or disintegration. In some cases, overspeed can also trigger safety mechanisms, leading to an automatic shutdown to prevent further damage. Maintaining proper operational speeds is crucial for ensuring the turbine's safety, efficiency, and longevity.
