The scary Sound of a damaged Generator Bearing inside a Windturbine

Sounds like Half-Life Anti-mass spectrometer starting up…

Oh wow. When I close my eyes I think I am hearing a jet engine. Sounds so much like a jet engine in a wind tunnel with massive echos!

[@echothefreak9396]

This is terrifying. I’m already scared of wind turbines, but am obsessed with them, but seeing them from the outside is enough. But being inside it hearing it starting up and all the sounds and everything… holy crap being inside those is one of my worst fears. Irrational fears, that is. Tall ceilings and large spaces or terrifying 😮‍💨

How can u be scared of wind turbines?

[@echothefreak9396]

@@frosty6960 Idk, I have a fear of large objects(I forgot what the phobia name is lol) or large empty spaces. It just seems eerie, like something is out of place. Oddly enough, whenever I drive by one I can’t take my eyes off of it. They’re scary but mesmerizing in way?? I can’t explain it

[@paulk8io445]

Sounds like my crappy lg front loader washer with its bad bearing. It was so loud you could hear it all over the house from the basement.

[@saasch_baasch]

Undamped Bearings on big hard structures is always a bad idea 😉

[@chutissimacrochet1678]

Tenía uno pero se explotó por acelerar demasiado no se como hice pero exploto

[@davidcoro27]

Except for the big bell like clang it sounds almost normal. However, a main bearing element that is damaged has the potential for a big problem

[@saasch_baasch]

Thanks to microphone auto processing this may sound something like normal, but in real this is anything like normal 😉

[@tfsplayer2275]

When i was about 5 i thought wind turbines generates wind 😆 and i relise it was the opposite

[@saasch_baasch]

You are a lucky one... I know people in the age of 30 who still think that they produce Wind 😄👍

[@jix177]

Exactly - because whenever they stop spinning there is no wind!

[@saasch_baasch]

This is the evidence! No doubts 😆

[@justynatumasz7858]

Whats this is a sound (high speed motor in 3 second) nearby windturbine?

[@brendanl3071]

Is that a v47/52? Keep pumping the generator grease. Will run for another 6 months. I changed generators bearing on a v47 in turbine before. It's an awkward job .

[@saasch_baasch]

😅 that's exactly what we did on this V90.... but at some Point the condition is going pretty fast, pretty bad. There are definitely way better jobs on the Turbine 😄

[@ruanjiayang]

Would this damaged bearing trigger shutdown or any kind of warning/fault?

[@saasch_baasch]

Not on this particular type of Turbine. On almost every newer one it would trigger some kind of alarm like "generator Bearing A excessive vibration" which is been measured by the condition monitoring system. This system is working with acceleration sensors on various spots. Enercon and Siemens DD Turbines are able to detect unusual and loud sounds via various microphones.

[@Tore_Lund]

So was this discovered during a routine inspection or are there temperature / vibration sensors on the bearings?

[@saasch_baasch]

In this Case it was discovered during an routine Inspection. On newer Turbines there is mostly a condition monitoring system, that measures constantly the Conditions of the critical Bearings with acceleration Sensors.

[@Mike-kr5dn]

How much power do turbines consume when idle? Do you know how much does 1 consume per year?

[@saasch_baasch]

This depends on the Type of Turbine and is between 1kW, up to ~15kW. In Production the own consumption is higher due to the Converter in operation, but this Energy is directly supplied by the own production. The consumption per Turbine per Year (means the periods there is no wind and the Aux systems of the Turbine have to be feeded by the Grid) depends highly on type and Wind conditions and vary between several 100 kWh up to 20 MWh, or In other Words between a shed and 5 Family houses. This may sound bad, but a Turbine is producing thousands of times the Energy which it consumes a year.

[@albertohr9930]

Esta turbina tiene un motor hidrauli o de 80kvas el convertidor para acoplar unos picos de 20 kvas odo depende del viento si es 3m/s acoplar y desacopla consume mucho

[@nathanieltaylor1995]

Kinda sounds like the THX logo

[@Mike-kr5dn]

How old was that bearing? That is concerning.

[@saasch_baasch]

The Bearing Was about 10 Jears old and did several billion rounds, it's OK for retirement. These can run up to several months with a damage before the mandatory exchange of the Bearing.

[@raysaunders5914]

@@saasch_baasch With respect, 10yrs isn't that long! Is it a design problem? I have no idea as to how long the bearings last in a 777 engine, but hopefully longer than 10yrs. From my perspective it's the 'perceived' difficulty factor in repairing the gearbox. Can the gearbox be removed /replaced without disturbing the blades?

[@saasch_baasch]

I am not working for MTU or Pratt and Whitney, but I am sure that the design requirements and the kind of Bearings used inside a PW4000 Turbine of a 777 is absolutely and totally different. Just imagine what could happen after a failure... Boeing: several hundred People in danger of live... Windturbine: some minor Power less in the Grid... I guess that the Bearings inside a PW4000 are hydrostatic and high performance Bearings, which are absolutely non comparable to the Windturbine "simple" ball Bearings. 10 Jears may sound short, but just do a small calculation: the average RPM of the Bearing is 1000 1/min. * 60 minutes * 24 hours * 365 days * 10 jears.... about 5 billion rounds. Do the same for the tire bearings on your car: around 750 1/min (17" tires and 60 kph average) * 5000 hours (that's 300,000 km at 60kph average) this is just 3,8 million rounds, that's factor of 1400, so this 10 jear old Windturbine is like a car with 420 million kilometers on the dashboard.... of course, the conditions of a car and a Windturbine different, but this is just an example of how much operating hours Windturbines do have after a short period of time. The Change of a generator Bearing can be done by two men, takes about 2 days (varying) and doesn't need a huge crane. Gearboxes may be changed without disassembling the Blades on most Turbines.

[@ThePerle1997]

Just a point from my side. Bearing in a 777 engine eg are getting changed after shorter period of time, as it’s mandatory for maintenance. A former colleague was working for a big plane turbine producer in Switzerland.

[@bowling6535]

Should have been shut down immediately.

[@Mike-kr5dn]

The bearing would be hard to fix, replacing it makes sense and before the part arrives why not keep running?

[@saasch_baasch]

Please keep in mind, that the Tower acts like a huge megaphone, that's why I recorded this there. The Damage is significant, but the Turbine don't have to be stopped, until the exchange of the Bearing some weeks later was done. The Sound right next to the Generator is much less terrifying😉

@@saasch_baasch It’s way too late, but I would have liked to hear what it sounds like from the top. This terrifies me as I have a phobia of big things/big spaces, but I CANT STOP LISTENING >:(

[@saasch_baasch]

@@echothefreak9396 I appreciate you passion 😉 I promise that I will do a record only for you the next time I am in an Turbine with an damaged Gearbox, bottom an Top for comparison. But to anticipate the Sound is much less terrifying, cause the huge echo chamber (whole Tower) does strange things to sounds emitted inside. For example if you shout to an colleague just 30 meters away in the Tower, you are barely able to understand just one word, cause everything sounds mixed and pitched down extremely. I do have a nice example of a huge Turbine in full production from the very bottom. You will love it I promise 😉
