Question 1 of 27070

The safety device provided on a turbo generator which closes the throttle automatically when the cooling water to the condenser is insufficient is called a/an __________.

🔍 Key Concepts

• Relationship between condenser cooling water and turbine exhaust pressure (back pressure) • Protective trips on steam turbine-driven generators • Effect of loss of condenser vacuum on turbine and boiler operation

💭 Think About

• If condenser cooling water is insufficient, what happens to the steam being exhausted from the turbine and the pressure in the condenser? • Which of these trips is specifically related to the exhaust/condenser condition, rather than speed, temperature, or general pressure in the system? • Which device would act before serious damage or loss of vacuum occurs when cooling is lost?

✅ Before You Answer

• Match the trip name to the location in the system: turbine inlet, turbine exhaust, condenser, or rotor speed. • Consider which condition changes first when cooling water flow to the condenser is reduced: vacuum/back pressure, temperature, or speed. • Verify which protective device is designed to prevent operation under high exhaust/back pressure due to poor condensing.
