Question 1 of 27070

A turbo generator back pressure trip can be actuated as a result of __________.

🔍 Key Concepts

• Condenser back pressure and how it is affected by condenser vacuum and circulating water flow • The relationship between exhaust steam pressure and turbine protection trips • What happens to turbine operation when condenser performance becomes poor

💭 Think About

• Ask yourself: if the condenser is not removing enough heat, what happens to the exhaust side pressure of the turbine and thus the back pressure? • Which option describes a condition that would make the turbine work against a higher pressure at the exhaust, potentially risking damage? • Which choices are about normal pressure drops or low pressures, versus a dangerous increase in pressure on the exhaust side?

✅ Before You Answer

• Identify which choice would cause loss of vacuum / rise in condenser pressure, not better vacuum. • Check which options actually increase back pressure on the turbine rather than decrease it. • Make sure the condition you pick is directly tied to condenser performance, not just valve position or normal turbine pressure drop.
