🔍 Key Concepts

• Turbine bearing overheating – what it usually indicates about lubrication and metal-to-metal contact • Lube oil system role – how lubrication, flow, and pressure protect bearings • Difference between reducing/stopping the turbine vs. correcting the cause of overheating

💭 Think About

• Before changing speed, ask: what most commonly causes a bearing to overheat in a turbine system? • Which action gives you the earliest indication of actual bearing damage (not just high temperature)? • Which option addresses both lubrication quality and evidence of damage rather than only changing load or cooling?

✅ Before You Answer

• Identify which choice directly checks for bearing damage indicators (e.g., metal particles) instead of only changing operating conditions. • Decide whether it is safer to immediately shut down or to first assess the condition while still maintaining control of the machinery. • Confirm which system (lube oil vs. cooling water vs. turbine speed) is the primary protection for bearings under normal operation.
