Q

A back pressure trip on an auxiliary turbo generator functions to secure the device if the __________.

🔍 Key Concepts

• back pressure in steam or exhaust systems • protection features on turbine-driven generators • effect of exhaust system restrictions on turbine operation

💭 Think About

• Think about what back pressure physically means in a piping or exhaust system. Does it refer to pressure at the inlet, inside the lube oil system, or at the discharge/exhaust side? • Which of these answer choices describes a condition that would make it harder for the turbine to expel its exhaust and could damage or slow the turbine if not corrected? • Which condition would be specifically monitored to prevent overload or damage to the turbine due to restriction in the exhaust path?

✅ Before You Answer

• Identify which choice refers to pressure on the exhaust or outlet side of the turbine, not the inlet or lube oil system. • Eliminate any options that deal with oil pressure or pump discharge pressure, since those are usually protected by different trips. • Focus on the option that describes pressure rising above a preset limit in the exhaust or return path, which is what ‘back pressure’ is about.
