Sample Punjab PSEB Sr. Sec. NSQF Power (Distribution Lineman) Practice Questions

Try these sample questions to review concepts for the Punjab PSEB Sr. Sec. NSQF Power (Distribution Lineman) exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1In a typical electric power system, the distribution stage is the part that:
A.Delivers electrical energy from substations to consumers at medium and low voltage
B.Generates electricity at the power plant only
C.Transfers bulk power over long distances at extra-high voltage only
D.Stores energy in pumped hydro reservoirs only
Explanation: Distribution is the final stage of the power system: energy leaves primary/secondary substations and is delivered to consumers on HT (medium-voltage) feeders and LT networks.
2On Indian distribution systems, low-tension (LT) supply to most domestic consumers is commonly about:
A.11 kV three-phase only
B.230 V single-phase / 400 V three-phase
C.66 kV only
D.220 kV only
Explanation: Low-tension consumer supply in India is typically about 230 V single-phase and 400 V three-phase (phase-to-phase), obtained after step-down by distribution transformers from HT feeders.
3A radial distribution feeder is best described as a feeder that:
A.Always has two independent sources feeding every consumer simultaneously
B.Exists only as underground cable and never overhead
C.Supplies consumers from a single path with power flowing outward from the source
D.Is used only for railway traction
Explanation: In a radial system, feeders branch outward from one source; each section is normally fed from a single path. This layout is simple but less reliable than ring or networked schemes if a fault isolates a branch.
4In Indian practice, a common primary distribution (HT) voltage for urban and rural feeders is:
A.230 V only
B.400 kV only
C.12 V DC only
D.11 kV
Explanation: 11 kV is a widely used primary distribution voltage in India for feeders that supply distribution transformers; lower voltages serve consumers after step-down.
5Compared with a pure radial feeder, a ring main distribution arrangement mainly improves:
A.Ability to restore supply from an alternate path after a section fault
B.Generator fuel efficiency only
C.Transformer oil acidity only
D.The need for earthing rods to zero only
Explanation: A ring main can feed sections from either direction, so operators can isolate a faulty section and often restore remaining consumers from the alternate path, improving reliability over pure radial feed.
6Three resistors of 6 Ω, 6 Ω, and 6 Ω are connected in parallel across a 12 V source. The total current drawn from the source is approximately:
A.0.5 A
B.6 A
C.2 A
D.12 A
Explanation: For three equal 6 Ω resistors in parallel, 1/R = 1/6 + 1/6 + 1/6 = 1/2, so R = 2 Ω. I = V/R = 12/2 = 6 A.
7A single-phase load draws 10 A at 230 V. The apparent power is approximately:
A.23 W
B.230 W
C.2.3 kVA
D.23 kVA
Explanation: Apparent power S = V × I = 230 × 10 = 2300 VA = 2.3 kVA. For single-phase circuits this product is the apparent power regardless of power factor.
8In a three-phase four-wire LT distribution system, the neutral conductor is primarily intended to:
A.Carry only lightning surge current and nothing else
B.Replace the need for any earthing electrode permanently
C.Carry only DC current from solar panels
D.Provide a return path for unbalanced phase currents and a reference for single-phase loads
Explanation: The neutral provides the return for single-phase loads connected phase-to-neutral and carries residual current when phases are unbalanced. Protective earthing is a separate safety function.
9Diversity factor on a distribution feeder is greater than 1 when:
A.The sum of individual maximum demands exceeds the maximum demand of the group as a whole
B.All consumers always draw full connected load at the same instant
C.Line resistance becomes zero
D.Voltage collapses to zero
Explanation: Diversity factor = (sum of individual maximum demands) / (maximum demand of the group). Because peaks do not all coincide, the group peak is smaller than the sum, so diversity factor is greater than 1.
10Voltage drop along a long LT distributor increases mainly when:
A.Conductor cross-section is made much larger with no other change
B.Load current and conductor resistance (or length) increase
C.All loads are disconnected
D.Only the earthing rod is shortened slightly
Explanation: Approximate voltage drop is proportional to current and to resistance of the path. Longer lines or higher load current increase drop; larger conductor size reduces resistance and therefore drop.

About the Punjab PSEB Sr. Sec. NSQF Power (Distribution Lineman) Exam

Punjab PSEB Senior Secondary NSQF Power is the Class 12 National Skill Qualification Framework trade (code 218) for the job role Distribution Lineman. It builds lineman-pathway knowledge and supervised workshop/field skills beyond Matric consumer energy meter work: electrical distribution system roles, overhead lines, poles and conductors, safety and PPE, earthing, tools, introductory distribution transformers, common faults, height-work awareness, electrical first aid, and Class 12 employability skills. Official assessment is Theory 40 + Practical 50 + INA 10 = 100. Pass requires at least 33% separately in Theory, Practical, and INA, and 33% aggregate per the Scheme of Studies. Fees and exact blueprints are notified by PSEB on pseb.ac.in. The 100 questions on this page are a free English-language multiple-choice study adaptation for theory concepts only; they are not a substitute for official practicals, viva, skill certification, or any licensed electrical work authorization. This bank is intentionally distinct from PSEB Matric NSQF Power (code 93) Consumer Energy Meter Technician.

Exam sponsor: Punjab School Education Board (PSEB). The requirements and fees below concern the certification or admission exam, separate from our free practice resources.

Assessment

Punjab PSEB Sr. Sec. NSQF Power (Distribution Lineman): Suggested Study Strategy

1Pair every MCQ category with school practical demonstrations — theory recall without supervised skill practice is incomplete for NSQF Power.
2Learn distribution system roles first (generation → transmission → distribution → consumer) so line and transformer questions stay in context.
3Treat PPE, isolation, and earthing as non-negotiable habits — many board and field questions start with safety judgment.
4Practise systematic fault response: make the area safe, report, isolate under authorization, then repair — never improvise on live systems.
5For height work, memorise belt/harness discipline, three-point contact ideas, and never climb without authorized support and inspection.
6Do not neglect practical and INA marks — they are 60 of 100 under the official Theory 40 + Practical 50 + INA 10 scheme.
7Keep this bank distinct from Matric Consumer Energy Meter revision: focus on Distribution Lineman lines, poles, earthing, and height safety language.
