1. A primary purpose of a yaw system in a wind turbine is to:

• Adjust blade pitch to optimize power
• Align the rotor with the wind direction
• Increase generator frequency
• Prevent lightning strikes

→ Ensures maximum wind exposure for energy production

• Lockout/Tagout (LOTO) procedures are used to: 1 / 4

• Warn workers about slippery surfaces
• Secure tools and equipment
• Control hazardous energy during maintenance
• Store fall-protection equipment

→ Prevents unexpected startup and electrical hazards

3. The term “cut-in wind speed” refers to:

• Minimum wind speed for braking
• Minimum wind speed required for power generation
• Maximum operational wind speed
• Wind speed at maintenance shutdown

→ Below cut-in, turbine cannot produce usable electricity

4. PPE for electrical work over 50V must include:

• Non-insulated boots
• Insulated gloves rated for voltage exposure
• Leather only gloves
• Sunglasses

→ Prevents electrical arc and shock injuries

5. A torque wrench is used to: 2 / 4

• Measure voltage
• Apply precise rotational force to fasteners
• Tension electrical cables
• Measure blade angles

→ Prevents under- or over-tightening of bolts

6. SCADA stands for:

• Systematic Cable and Distribution Automation
• Safety Control and Diagnostic Access
• Supervisory Control and Data Acquisition
• Secondary Control and Deployment Access

→ Used for monitoring and remote turbine control

7. Hydraulic accumulators serve to:

• Generate heat
• Store pressurized hydraulic fluid for system stability
• Convert hydraulic pressure to electricity
• Lubricate bearings

→ Provides immediate force and pressure smoothness

8. Fall protection is required above: 3 / 4

• 2 ft
• 4 ft
• 6 ft
• 12 ft

→ OSHA mandates fall protection at 6 ft or higher

9. A megohmmeter (“megger”) is used to:

• Check hydraulic pressure
• Test pH of coolant
• Measure torque on bolts
• Test insulation resistance

→ Ensures wires/cables are not shorting to ground

10. A brake system in a turbine mainly:

• Charges batteries
• Stops or slows rotor during faults/maintenance
• Increases blade pitch
• Removes blade ice

→ Critical for safe shutdown

11. The generator in most large turbines is:

• / 4
