How Can You Use Articulating Borescope for Wind Turbine Inspection?

People are now switching to wind turbines as they want to be a part of more environmentally friendly option for obtaining power. They will make use of wind power to create a better and cleaner energy, which can also be more cost-effective as compared to oil or coal.

However, wind turbines need inspection while performing their regular maintenance, or for repair if something is broken. With proper inspection you can ensure that your equipment will meet its life expectancy as well as give its best performance.

By using borescope camera from USA Borescope, you can make your inspection job much easier and also safe for the operator.

How borescope image can help you?

Pitting can be a failure mechanism for material fatigue, which can either be micro-pitting, macro-pitting or it can be mixture of both.

Often an oil droplet, which is normal, but it may appear as pit or dent. You may view the entire original grinding marks at the dent base. A dent also offers a clue that somewhere else in the gearbox any failing component may be producing debris.

In such case an additional search by using the borescope will be needed in order to locate the source of debris.

Modern borescopes can actually videoscope and also save digital snapshots obtained from the video. With increased amount of light output, videoscope hardware will continue to advance, and offer high image quality with improved view.

Despite such improvement often there is blurring of images due to camera tip gets fouled with bearing surface or oil that reflect the adjacent features like mirror. Due to magnification of image, it makes difficult to judge scale.

Few helpful assessment questions may include:

  • Do the entire original grinding lines of manufacturing exist in its feature or whether they are just interrupted?
  • Is there any darker color around outer edges of feature?
  • Does the light that is reflected from camera look continuous or it is bent around its feature?
  • Does inside feature appear shiny, grainy, cratered or dull?

Often feature in borescope image may simply be suspicious and unidentifiable. You can categorize it ‘unusual marking’ and then recommend for another inspection within 12 months.

How to use articulating borescope for inspecting wind turbines?

An articulating borescope can make inspection of all components much easier and you will not need to disassemble it. Articulating borescope will allow you to see gearboxes, blades etc. Following are few things to remember.

  1. Ensure that your battery is completely charged

Often it may take many hours to inspect all the components of wind turbine. So, if you do not want to stop in the middle of the job, charge your battery fully.

  1. Try to extend the tube by inserting probe into the entry point

Based on which system of wind turbine you are inspecting you will need to extend fully the probe and also carefully guide into the entry point. Don’t damage your optics of borescope and proceed carefully.

  1. Take your time to inspect the systems

Looking at the size of wind turbine, these systems are not so complex, but a bit large. Most operators will check at a time one system so they will not miss anything.
