Triveni Engineering & Industries Turbine DCS Engineer Interview Questions and Answers

Vaccum drop in a turbine can be caused by air leakage, steam leakage, or malfunctioning equipment.

• Air leakage in the system

• Steam leakage in the system

• Malfunctioning equipment such as valves or seals

• Low condenser vacuum due to cooling water temperature increase

• High turbine exhaust pressure

Downtime costs include lost production, repair expenses, and potential damage to reputation.

• Calculate lost production revenue during downtime

• Consider repair expenses for fixing the issue causing downtime

• Factor in potential damage to reputation and customer trust

• Implement preventive maintenance to reduce downtime costs

• Invest in spare parts inventory to minimize downtime
