What is Transformer Rectifier Unit (TRU) || Construction & Working of TRU || How to make a TRU ?

[@prasann003]

I believe the output here would be 270V not 26V. Please explain if I am wrong.

[@aviatorupdates]

This is a typical type of TRU wherein the output is 26V. Based on the requirement, the device with the required output can be designed.

[@sarathsrinivas2095]

sir you are always best..the way you draw diagram while explaining, its makes very very easy for us to understand...

[@aviatorupdates]

Thank you so much dear @Sarath. Hope you are doing great. Keep learning 😊

[@owinookello9358]

great teacher slow but sure keep giving many videos

[@aviatorupdates]

Thank you for the value and appreciation. We will surely make new video sessions and try to be consistent in it.

[@jagdishpande4336]

Very informative 🙌🏻Thank you for video Sir.

[@aviatorupdates]

Welcome dear 😇. Keep learning and keep growing your knowledge. Thank you 😊

[@tanujkumar7568]

Excellent explination

[@aviatorupdates]

Many thanks dear. Keep learning 😊

[@dreamerseas5973]

Thanks for the great vid, very well explained

[@aviatorupdates]

Welcome 🤗 and thank you for the compliment for the session. Keep learning 😇

What is the purpose of the Wye and Delta secondary. Why 26 volts output that is worthless why not 200 volts or more. I guess same could be said for the input voltage.

[@aviatorupdates]

Wye & Delta connections are 3-phase connections. Hence used in the diagram. 2 different secondary windings are used because star and delta connections both have their individual benefits; star connection has a ground terminal and delta connection is better for unbalanced load. The explanation here is about a typical TRU having input as 200V ac and output as 26V dc which is a unit used in aircraft. For commercial applications, the input and output can vary and be equal to the values you mentioned in your comment. The no. of windings and design may also vary in the such a TRU. The working principle would remain the same. Thanks for watching our video. Keep learning keep growing 🤗

Thanks a lot sir.

My concern is in thermal switch will be shorted the positive and negative when they are activated..?

[@aviatorupdates]

The electrical supply (D.C.) from an external bus bar is always ON/LIVE and flows through the wiring of warning circuit but as the thermal switches are not closed (shorted) in normal operations, this electrical supply (D.C.) waits at one of the contact point of the thermal switches. The moment there is overheating of the T/F or the rectifier, the thermal switch comes in action and it closes (gets shorted) both contact points of the respective thermal switch. Since the warning circuit is closed now, immediately the electrical supply (D.C.) which was waiting at one (note: a switch has 2 contact points) of the contact point of the thermal switches will now have a path (as both contact points of the thermal switches are connected now) to flow through the warning circuit and hence the warning will be triggered immediately ( on the closing or shorting of the thermal switch contacts). Note: The thermal switches are activated during overheating of T/F and/or rectifier when temperature conditions at their respective locations rise to approximately 150°Cand 200°C.

Super... Sir... Thank you🙏🙏🙏

[@aviatorupdates]

Thank you

[@najim9223]

Nice video😆

[@vedantshah_]

How are we able to connect output of both the rectifiers in parallel as they have unequal voltages, will it not result in circulating current?

[@aviatorupdates]

Nice question! In the diagram explained the rectifiers used are all of the same electrical rating.

[@ruhiparmar9978]

Great sir !!!!

[@aviatorupdates]

Thank you

[@SandeepSingh-km1fs]

is there necessay to be used two secondary winding???

[@aviatorupdates]

It is not necessary as such; but if more output voltage is required, it is a good idea to have 2 or more windings in secondary. In the video, I have shown only 2 windings on secondary (a typical TRU).

[@trims9833]

Well explained 🙂 can u make a video for single phase transformer rectefier unit

[@aviatorupdates]

Yes sure. Will do it soon. Stay tuned 😇

[@trims9833]

@@aviatorupdates waiting sir 🙂

[@owinookello9358]

kindly also make how the transformer rectifer unit is connected to esp

[@owinookello9358]

hahah nice bro big up

[@SandeepSingh-km1fs]

why u used two different secondary windings in transformer ??

[@aviatorupdates]

2 different secondary windings are used because star and delta connections both have their individual benefits; star connection has a ground terminal and delta connection is better for unbalanced load.

[@owinookello9358]

kindly make a grid rotor resistance starter wiring and its theory sir

[@laxmanmanne7817]

🙏🙏🙏

[@aviatorupdates]

Thank you 😊.

[@MAYANKKUMAR-ef9dm]

400 hz??

[@aviatorupdates]

Yes correct dear ! You can consider the AC input frequency to the TRU as 400Hz. If you want to learn more about 400Hz, check this link kzbin.info/www/bejne/iKm1moqKj52ZsNE
