How to use this guide
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.
Identify source and role
Separate issuer, state authority, competent person, operator, and supervisor boundaries.
Lock field controls
Check isolation, PPE, instrument readings, exposure, clearance, permits, and emergency routes.
Close with records
Protect certificates, logbooks, registers, test sheets, incident notes, and correction records.
Authorization and Permit Boundary
Confirm who may operate, isolate, test, issue permits, receive permits, and restore plant or substation equipment.
Key rules
Rule 1
Issue or accept the permit only after authorized isolation, identification, earthing where required, and permit receiver confirmation are complete.
Exam cue: permit issue boundary
Rule 2
Keep switching and restoration under an authorized operator; trainees may assist only within supervised limits.
Exam cue: authorized operator
Rule 3
Do not energize until the permit is returned, workers are clear, tools and earths are accounted for, and restoration authority is recorded.
Exam cue: permit return before energizing

Simulation focus
Authorization and Permit Boundary
Confirm who may operate, isolate, test, issue permits, receive permits, and restore plant or substation equipment.
Common traps
Treating verbal permission as written authorization.
Prevention: Avoid verbal approval, copied readings, skipped isolation, and after-the-fact record traps.
Proceeding without recording readings, isolation, PPE, or exposure-control evidence.
Prevention: 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.
Prevention: Avoid verbal approval, copied readings, skipped isolation, and after-the-fact record traps.
Memory anchors
permit issue boundary
Issue or accept the permit only after authorized isolation, identification, earthing where required, and permit receiver confirmation are complete.
authorized operator
Keep switching and restoration under an authorized operator; trainees may assist only within supervised limits.
permit return before energizing
Do not energize until the permit is returned, workers are clear, tools and earths are accounted for, and restoration authority is recorded.
switching instruction
Use an approved switching instruction or emergency protocol, identify equipment positively, and record each step as performed.
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.
