• What is the primary purpose of a nacelle on a wind turbine?
• To support foundation loads
• To house major turbine components such as the gearbox and

generator

• To measure wind direction
• To anchor blades during shutdown

Rationale: The nacelle contains and protects critical mechanical and

electrical components.

• Which electrical unit measures current flow?
• Volts
• Amperes 1 / 3

• Ohms
• Watts

Rationale: Current flow is measured in amperes (amps).

3. Lockout/Tagout (LOTO) procedures are used primarily to:

• Improve communication
• Speed up maintenance
• Prevent unexpected energization of equipment
• Control fall hazards

Rationale: LOTO ensures equipment cannot be powered during

servicing.

4. The anemometer primarily measures:

• Air temperature
• Wind direction
• Wind speed
• Blade pitch

Rationale: Anemometers detect wind velocity to optimize turbine

performance.

• Which part converts rotational mechanical energy into electrical

energy?

• Hub
• Gearbox
• Generator 2 / 3

• Pitch motor

Rationale: The generator creates electricity from rotational input.

6. A wind turbine typically shuts down during high wind speeds to:

• Increase power output
• Protect components from damage
• Avoid wildlife interference
• Prevent tower oscillations

Rationale: Overspeed can cause mechanical failure.

7. PPE required when climbing includes:

• Hard hat only
• Safety glasses only
• Full fall-arrest system
• Flashlight only

Rationale: Fall-arrest is required for working at heights.

8. Blade pitch control adjusts:

• Tower vibration
• Angle of the blades to wind
• Generator load
• Gearbox lubrication

Rationale: Pitch changes allow optimal rotation and shutdown.

• Which tool measures electrical resistance?
• Tachometer
• Infrared camera
