1The SI unit commonly used on consumer electricity bills for energy is the:
A.Kilowatt-hour (kWh)
B.Volt only
C.Ampere only
D.Ohm only
Explanation: Utilities bill active energy in kilowatt-hours. One kWh is one kilowatt of power used for one hour.
2Energy in kilowatt-hours is most correctly related to power and time by:
A.Energy (kWh) = Power (kW) ÷ Time (h)
B.Energy (kWh) = Power (kW) × Time (h)
C.Energy (kWh) = Power (kW) + Time (h)
D.Energy (kWh) = Voltage only
Explanation: Active energy equals average active power multiplied by operating time when units are consistent (kW and hours).
3A consumer energy meter’s main purpose is to:
A.Generate electricity for the grid
B.Replace the distribution transformer
C.Record electrical energy consumption for billing and monitoring
D.Control only the speed of motors
Explanation: Consumer meters measure and register energy used at the premises so the utility can bill and monitor usage.
4In Indian LV consumer metering practice, a typical single-phase meter is associated with a:
A.Twelve-wire industrial bus only
B.Only DC traction network
C.Only high-voltage transmission line without neutral
D.Two-wire system (phase and neutral)
Explanation: Single-phase LV consumer meters are used on two-wire phase-and-neutral supplies common in homes and small loads.
5A typical three-phase LV consumer energy meter for many commercial loads uses a:
A.Four-wire system (three phases and neutral)
B.One-wire system only
C.Only a wireless radio with no phases
D.Only a battery with no AC supply
Explanation: Three-phase four-wire LV metering covers three live phases plus neutral for balanced and unbalanced consumer loads.
6Before starting meter installation work, a technician should first:
A.Ignore paperwork and start cutting cables
B.Obtain the job specification or work order from the responsible authority
C.Remove all seals without documentation
D.Bypass the isolation procedure permanently
Explanation: Work must start from an authorized work order so the correct meter, location, and safety steps are known.
7Which item is essential PPE for live electrical meter work risks?
A.Cotton scarf only with no gloves
B.Metal jewelry for better contact
C.Insulating rubber gloves rated for the task, with other required PPE
D.Wet bare hands for grounding
Explanation: Insulated gloves and complementary PPE (footwear, eye protection, hard hat as required) reduce shock and arc-related injury risk.
8kVA primarily measures:
A.Only cable color
B.Only magnetic north
C.Only ambient humidity
D.Apparent power
Explanation: Kilovolt-ampere (kVA) is the unit of apparent power (voltage × current, with appropriate three-phase factors).
9Power factor is best described as the:
A.Ratio of active power to apparent power
B.Ratio of cable length to pole height
C.Number of meter seals only
D.Color of the meter body only
Explanation: Power factor = kW/kVA (for sinusoidal cases, cos φ). It indicates how effectively current produces useful power.
10When reading a traditional dial or digital cumulative energy register, the technician should primarily record the:
A.Only the outdoor temperature
B.Present cumulative kWh reading as per utility procedure
C.Only the brand logo color
D.Only the pole number of a distant feeder
Explanation: Billing and verification depend on the meter’s cumulative energy register (kWh), taken carefully and as trained.
