1In the electricity supply chain, which stage steps voltage down near consumers for local delivery?
A.Distribution
B.Generation
C.Bulk transmission only
D.Fuel procurement
Explanation: Distribution is the final stage that steps voltage down and delivers electricity to homes and businesses through feeders and service lines. Generation produces electricity; transmission moves bulk power at high voltage.
2Which voltage class is typically associated with long-distance bulk transmission rather than household service?
A.230 V single-phase domestic supply
B.Extra-high voltage (EHV) transmission levels
C.415 V three-phase low-voltage supply
D.12 V battery-pack electronics
Explanation: Long-distance bulk power moves at high and extra-high transmission voltages. Domestic service is usually about 230 V single-phase (or 415 V three-phase low voltage), not EHV.
3What is the main role of a distribution company (DISCOM) in the power sector?
A.Building only nuclear reactors nationwide
B.Printing currency notes for electricity bills
C.Retail supply and distribution of electricity to consumers in a licensed area
D.Manufacturing only wind-turbine blades
Explanation: DISCOMs (distribution licensees) operate distribution networks and supply electricity to consumers in their licensed area under regulation. Generation companies build plants; DISCOMs handle last-mile delivery and retail supply.
4Historically, early public electricity systems first focused on which consumer need?
A.Instant global internet data centres only
B.Household air-conditioning everywhere from day one
C.Space-satellite propulsion power
D.Lighting and basic public/industrial power use
Explanation: Early public electricity systems primarily served lighting and then expanded industrial and general power uses. Modern loads such as data centres and mass AC came much later.
5In a simplified radial power system path, which order is correct from plant to home?
A.Generation → Transmission → Distribution → Consumer service
B.Consumer service → Transmission → Generation → Distribution
C.Distribution → Generation → Consumer service → Transmission
D.Transmission → Consumer service → Generation → Distribution
Explanation: Power is generated, stepped up and transmitted in bulk, then stepped down and distributed, and finally delivered on the consumer service connection.
6What does “low voltage” (LV) generally mean in the context of consumer meter installation for Class 10 NSQF Power?
A.Only voltages above 220 kV
B.The voltage level used for most domestic and small commercial service connections
C.Only voltages inside a mobile phone battery
D.Any voltage that cannot cause injury
Explanation: In distribution practice, LV refers to the low-voltage network used for typical domestic and small commercial services where consumer energy meters are installed. It is not EHV, and LV can still be hazardous.
7Why are step-down transformers used in distribution substations?
A.To increase domestic voltage to transmission levels at every home
B.To convert electricity into petroleum fuel
C.To reduce high distribution/primary voltages to usable LV service levels
D.To eliminate the need for any protection devices
Explanation: Step-down transformers lower voltage from higher distribution/primary levels to service voltages suitable for consumer equipment. Homes are not stepped up to transmission voltage.
8Which statement best describes a feeder in power distribution?
A.A device that only measures rainfall at a plant
B.A tool used only for soldering electronic chips
C.A legal form for school admission
D.A circuit that carries power from a substation out toward load areas
Explanation: A feeder is a distribution circuit leaving a substation (or similar source) to supply a load area. It is an electrical network term, not weather gear or paperwork.
9What is a key difference between single-phase and three-phase low-voltage supply for consumers?
A.Three-phase supply uses three live phases (plus neutral as applicable) for higher capacity loads; single-phase uses one phase and neutral for typical domestic loads
B.Single-phase always has higher capacity than any three-phase service
C.Three-phase means zero voltage at the meter
D.Single-phase can only be used for street lighting, never homes
Explanation: Single-phase LV service (one phase + neutral) suits most homes. Three-phase LV service provides three phase conductors (with neutral as designed) for larger loads such as motors and bigger commercial installations.
10In NSQF Class 10 Power, the vocational focus is closest to which job-role pathway?
A.Independent licensed electrical contractor for all building wiring without limits
B.Consumer energy meter technician skills for LV metering work under DISCOM processes
C.Nuclear reactor operator certification
D.Aircraft maintenance engineer licensing
Explanation: BSEH Secondary NSQF Power (code PWR 986) centres on power-distribution and consumer energy meter technician competencies (e.g., PSS meter and safety NOS), not full licensed electrician contracting, nuclear operations, or aviation maintenance.
