6 FAQs about [Causes of fire in wind turbine generators]

Why do wind turbines catch fire?

Do wind turbines cause fire accidents?

By comparison, with other energy industries, fire accidents are much less frequent in wind turbines than other sectors such as oil and gas, which globally has thousands of fire accidents per year. However, fire accidents can have a considerable economic impact on the wind farm industry, say the team.

What causes fire ignition in wind turbines?

The researchers also outline the main causes of fire ignition in wind turbines in the study. They are, in decreasing order of importance: lightning strike, electrical malfunction, mechanical failure, and errors with maintenance.

What causes a turbine to fire?

Failures can occur in various parts of the turbine and for different reasons. Gear wear or damage, bearing overheating, fatigue, using the wrong oil or wrong oil temperature, vibrations, and overload are some of the most common causes of fires.

What are the most common causes of wind turbine accidents?

Blade failure was the highest cause of accidents, which showed 15% of the total accidents. The second most common cause is fire accidents, which included 14% of the total number of global wind turbine accidents. The third most common cause of accidents was structural failure, which was 7% of the total accidents.

What happens if a wind turbine blade fails?

For the wind industry, the fires are the second leading cause of accidents after blade failure. Inside of the turbine’s nacelle, hydraulic oil and plastics share the same tight space as machinery and electrical wires. When there is overheating or faulty wiring it can catch fire.
