Suzlon Wind Technician Certification Exam Practice Questions And Correct Answers (Verified Answers) Plus Rationales 2026 Q&A | Instant Download Pdf
- What is the primary function of a nacelle in a wind turbine?
- Support the tower
- Store generated power
- House major mechanical and electrical components
- Control blade pitch
Rationale: The nacelle contains key components such as gearbox,
generator, and control systems.
- Which component adjusts the blade angle to control power and loads?
- Gearbox
- Pitch system
- Yaw bearings 1 / 3
- Anemometer
Rationale: The pitch system rotates blades around their axis to optimize
aerodynamic performance.
3. The yaw system is responsible for:
- Stopping the turbine during high wind
- Orienting the rotor into the wind
- Supporting the main shaft
- Adjusting rotor speed
Rationale: Yaw motors and gears rotate the nacelle so blades face the
wind direction.
- Which type of braking system is used for emergency stopping?
- Aerodynamic only
- Hydraulic only
- Mechanical disc brake
- Electrical resistance brake
Rationale: Mechanical brakes provide reliable backup braking during
faults.
5. Typical cut-in wind speed for large turbines is:
- 1–2 m/s
- 3–4 m/s
- 6–7 m/s
- 10 m/s
Rationale: Turbines begin generating power around 3–4 m/s. 2 / 3
- What is the cut-out wind speed for most utility-scale turbines?
- 10 m/s
- 15 m/s
- 25 m/s
- 35 m/s
Rationale: Turbines stop above ~25 m/s to protect equipment.
- Which gearbox design is most common in Suzlon wind turbines?
- Direct drive
- Friction gear system
- Planetary-parallel combination
- Worm gear
Rationale: Planetary stages allow compact design and high torque
transmission.
8. The main shaft connects the rotor hub to the:
- Control cabinet
- Tower foundation
- Gearbox
- Yaw drive
Rationale: The low-speed shaft transfers rotor torque into the gearbox.
- Which generator type is widely used in Suzlon turbines?
- DC generator
- Squirrel cage induction generator
- Doubly-fed induction generator (DFIG)
