Linemen 12 kV Parts Exam Questions
With All Correct Answers Verified
Answers 2025 Marking Scheme New
Update
Insulator - Answer- A device used to support and insulate electrical conductors,
preventing unwanted current flow to the ground.
Circuit Breaker - Answer- An automatic switch that interrupts the flow of electricity in
case of an overload or short circuit.
Transformer - Answer- A device that changes the voltage level of electricity, either
stepping it up or down for distribution.
Voltage Regulator - Answer- A device that maintains a constant voltage level to protect
equipment from voltage fluctuations.
Fuses - Answer- Safety devices that protect electrical circuits by melting and breaking
the circuit when excessive current flows.
Recloser - Answer- An automatic device that closes a circuit after it has been opened
due to a fault, allowing for temporary interruptions.
Capacitor - Answer- A component that stores electrical energy and helps improve power
factor and voltage stability in the system.
Switchgear - Answer- A combination of electrical disconnects, fuses, and circuit
breakers used to control, protect, and isolate electrical equipment.
Grounding System - Answer- A system that connects electrical equipment to the ground
to ensure safety and prevent electrical shock.
Busbar - Answer- A conductive material that serves as a common connection point for
multiple circuits, distributing electrical power.
Line Post Insulator - Answer- An insulator mounted on a pole or tower that supports
overhead power lines and prevents electrical leakage.
Deadend Structure - Answer- A support structure used to anchor the end of a power
line, preventing it from sagging or breaking under tension.
