← TechnologyWhich surge consequence results when wind turbine blades rapidly accelerate?
A)Gearbox torsional overload failure✓
B)Generator over-speed shutdown enacted
C)Hydraulic pitch system lockup
D)Yaw bearing excessive thermal expansion
💡 Explanation
Rapid blade acceleration causes resonant vibrations transferred throughout the drivetrain; therefore, gearbox torsional overload occurs because mechanical resonance amplifies torque spikes; rather than electrical or thermal effects directly initiating without component fatigue.
