🔍 Key Concepts

• Generator bearings and lubrication – what conditions cause sludge to form in lubricating oil and lead to rapid bearing failure • Electrical grounding/insulation of bearings – why one end of some generators is insulated and what happens if that insulation fails • Symptoms vs root cause – difference between treating the symptom (failed bearing) and correcting the underlying cause

💭 Think About

• Which choice deals directly with a condition that could cause electrical current to pass through the bearings and damage both the bearing and the oil? • If the oil is sludging, is it more likely a purely mechanical problem with the bearing type, or could heat/electrical arcing in the bearing be degrading the oil? • Which option looks like it corrects an underlying design/insulation issue on the generator itself, rather than just replacing parts or checking unrelated connections?

✅ Before You Answer

• Verify which end of a generator often has an insulated bearing and why this is done in relation to shaft currents and grounding • Check which options actually address lubricating oil breakdown versus those that only address mechanical replacement or unrelated electrical connections • Confirm which action would most directly prevent repeated bearing failures and oil sludging, not just fix a single failed bearing
