Abnormal Readings and Restoration
Respond to voltage dips, unbalance, harmonics, overheating, low oil pressure, alarms, restoration sequencing, and load priority.
How to study for generator and substation operation
Practice like an authorized operator: lock the source, follow switching sheets, control permits, test before touch, protect DC supply, read protection signals, restore loads safely, and keep logs that survive inspection.
Core concepts
Concept 1
Investigate unbalance, neutral loading, loose connections, and load distribution before equipment overheats or protection operates.
Exam cue: phase unbalance
Concept 2
Review starting method, load impact, voltage limits, failed-start count, and authorized mitigation before repeated attempts.
Exam cue: motor-start voltage dip
Concept 3
Treat low oil pressure as a shutdown or no-load condition under procedure until lubrication is verified.
Exam cue: oil-pressure alarm

Risk pitfalls and guardrails
Treating verbal permission as written authorization.
Guardrail: Avoid verbal approval, copied readings, skipped isolation, and after-the-fact record traps.
Proceeding without recording readings, isolation, PPE, or exposure-control evidence.
Guardrail: Avoid verbal approval, copied readings, skipped isolation, and after-the-fact record traps.
Choosing a generic answer without checking state variation or the latest official notice.

Memory anchors
phase unbalance
Investigate unbalance, neutral loading, loose connections, and load distribution before equipment overheats or protection operates.
motor-start voltage dip
Review starting method, load impact, voltage limits, failed-start count, and authorized mitigation before repeated attempts.
oil-pressure alarm
Treat low oil pressure as a shutdown or no-load condition under procedure until lubrication is verified.
restoration priority
Restore according to approved priority, available capacity, inrush limits, safety checks, and communication with affected users.
Official source check
Verify eligibility, forms, fees, validity, and safety requirements with Central Electricity Authority / State Electrical Inspectorates or the current state authority notice.
Stop-work cue
If identity, authorization, isolation, PPE, exposure limits, or emergency controls are unclear, stop work and escalate.
Record cue
Exam-safe answers protect written records, competent sign-off, instrument readings, and traceable corrections.
Shortcut trap
Fast results, verbal approval, copied certificates, and undocumented adjustments are common trap answers.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
