Function Principle of the OLTC

[@bachaoxuan5093]

The definition of OLTC in Wikipedia is difficult to understand. This vid is very clear. Great!

[@ReinhausenTV]

100.000 views! Many thanks to everyone

[@leemurray9330]

Thank you so much! Explained it wonderfully.

[@VijayMachhar]

*Wow. Amazing explanation using animation , plz make more animated video based on technology* *That students can learn easily*

[@ΑναστάσιοςΚλαδάς]

Great video! Simple and understandable!

[@Gameboygenius]

Why is it called Vacutap? Is the transformer kept in a vacuum to avoid arcing? If so, for how long can you guarantee that a suitable vacuum is maintained before the transformer needs maintenance?

[@median_hp]

if the arc happens in the vacuum did i still needs to check my the oil compartment of the OLTC (BDV/DGA)? because it will reduce our cost significantly if we didn't needs to do check again :D

[@ReinhausenTV]

Thanks for your comment, we are pleased, that the video helps to understand.

[@ReinhausenTV]

Thank you! Have you already seen the video of on-load tap-changer maintenance in48 hours?

[@BarneySaysHi]

Cool video with cool music!

[@median_hp]

thank you so much for uploading this, i have a vacutap and i'm still confused because it still needs oil. after watching this i guess it means that the diverter switch done in a vacumm but the selector switch still immersed in the oil. is it true?

[@PrashanthGopal]

Excellent piece of animation, well explained!!

[@venomdark23]

Very nice... keep uploaded....

[@AsanMasraf]

thanks for this filmographic, but I wonder why always tap no. it comes in ODDs not even, such as; 11,13,15,17,19..etc.

[@anikidwolfy]

thanks for the vid - MADE ME UNDERSTAND WHAT IT DOSE AND HOW IT WORKS

[@ReinhausenTV]

Thanks for your comment. We are pleased, if it is helpfulfor you.

[@Mr63001]

Thanks for Clear explain to the Principles of Technology of How it works

[@ReinhausenTV]

It is called VACUTAP® because the operation of tap-changing is done in a vacuum.

[@ReinhausenTV]

Almost right. The transformer as well as the oil compartment of the OLTC are filled with insulating oil. Inside of the oil compartment there is the diverter switch insert (under oil). The diverter switch insert contains the vacuum interrupter. The making and breaking of the arc happens in the vacuum interrupter with vacuum as arc quenching media.

[@ReinhausenTV]

In fact you can save the money for the DGA. However the breakdown voltage has to be checked. For Y-applications with a regulation in the Y-point (IEC 60214-1 - Class 1) it shall be 30kV/2,5mm. For other applications (IEC 60214-1 - Class 2) it shall be 40kV/2,5mm (measuring method with spheric electrodes according to IEC 60156).

excellent video keep uploaded

[@MabitselaD]

Hi What sotware did you use for animation

[@CaoHuy2310]

Thank u. It helped me a lot in understanding.

[@ReinhausenTV]

@okmyfriendful Thank you for your comment. Of course we keep it on kzbin.info. We are planning to update this channel regularly. So visit us again.

[@shahzaibshahid7275]

increasing taps decreases the no of coils in HT transformer???

[@Eric_Dan-6_MD_PhD]

+Shahzaib Shahid Yes.

[@haowang1651]

The definition of VACUTAP is perfect! What software is used to make this great animation?

[@ReinhausenTV]

Thank you very much, Hao Wang. The animation was produced by an agency specialized in video applications

[@sourabh669]

why 9a, 9, 9b this three tap positions are used in 9th tap in a 132kv transformers

[@Foreveradeel]

Tape changer MDU and tape changer accurate position setting video plz

[@ReinhausenTV]

That's great to hear!

[@deepika00001]

super explanation... gr8

[@w5cdt]

Nice animation!

[@vitalysavicks6756]
