the overhead cables are not central they are put in a zizag orientation to prevent the wear in one place
Yep.
Correct 💯
Very true.
Logical…but not obvious. Thank You !
In Poland they are central 🤔
Friends, I am trying to explain this video in an organized way but, if there is any mistake I am sorry for that.
Really I love it to make these videos. Please share your knowledge regarding Pantograph or Childhood thinking.
You are doing a very good job, and are to be commended for that. I feel you left out some important parts, but I understand this is an introductory video, and you need to keep it short.
You've made great video

W$#$%
That's a great description thanks, but what about completing the circuit, only one side of the power comes from the pantograph (positive?) where does the other side (negative?) come from, the rails?
Great introductory video, very good animation and commentary 👏👌
1:52 - carbon strips alao wear out faster, while rubbing against the catenary wires that are made of copper alloys. The former are easier to replace than the copper wires, that would require extensive efforts, besides being very expensive.
I give you several points for the excellent name of your channel!
I would like to point out that "pantograph" is the name of a particular type of mechanism. The pantograph on an electric locomotive is only one instance of this mechanism. Pantographs are also used as drawing instruments for mechanically enlarging or reducing the size of a design, and for several other purposes. You description makes it sound like there is only one kind of pantograph.
The important point of a pantograph mechanism is pair of linked arms that maintain a fixed relation to each other as they pivot. You see that in a locomotive pantograph because the knuckle is always half way between the top of the base and the collector arm in height. If it were not for the pantograph arm linkage, the bottom could hinge up too high and the knuckle would contact the wires, which would be bad.
There is 2type of panto graph but, we only type of in many places ,it was very rare to see the 2 nd type of pantograph
So, it was proved that we should not comment the wrong lessons
Untill we learn tq
GOOD 👍👍
The explanation is a bit superficial, then followed by a passing reference to capacitors and other items that the viewer may not know about. I would start again if I were you after reading how the mechanism operates.
Good explanation. Really appreciate the construction of this clip.
In future, if more info on :
1) how the electric part of the pantograph relays electric power to the onboard transformer ... goes from wheels to the track to form a complete circuit
2) difference between pantographs for dc & ac tracks
That would be great.
Informative
awason vieo good explanation
Really awesome
Further details in how the compressed air lifting details are needed since I am designing a pantograph for my model electric loco wherein I wish to incorporate the lifting mechanism with the help of springs and servo motor and flexible upper arm. Will you put up an video on how exactly the lifting mechanism works. Though I cannot imagine to go in for miniature compressed based mechanism I can try with servos and spring loaded lifter arm using Plunger type arm for it.
Very well made video......
❤❤
in the US the pantographs are lifted by air, so if a line breaks while traveling the pantograph drops which prevents farther damage to the power car, pantograph and catanary.
Awesome chiranjit bhai....
Good explain about pantograps
Awesome 👌
Thank you very much Sir .. ❤️
The way you explain is awesome through animation video everyone get the needful information about how pantograph work .. literally I'm very curious about to know how it works and you explained it beautifully .. once again thank you very much ❤️. 🙏🙏
Very informative video.
Awesome
Super video. Thank you. Огромное спасибо!
Wonderful Information
Very informative ..... I was totally unaware of this Pantograph....... I was thinking it simply touches the over head high voltage transmission line .....
Your explanation is awesome and it is very easy to understand sir thank you very much
Very nice
Nice video, learnt a lot through this video!
In the Southern region in England, we have another form of electric power system known as Third Rail. It’s basically a third rail which supplies electricity and there is a shoe collecting the electricity to supply power
There are actually 3 types: an overhead system (and I don't mean a wired system like here in the video), a midrail system and a sideways rail system and in the metro of Lyon (though I thought Paris had that too) a variation to it, so it can run on tires and is guided along with it. (There also combined ones nl.wikipedia.org/wiki/Derde_rail#/media/Bestand:EalingCommon3.jpg). The sideways rail is being used by underground trains like in The Nederlands. commons.wikimedia.org/wiki/File:Third_rail_vienna_2.jpg (it's also showing what's inside).
Third rail is not suitable for main line operation. It effective only in Urban rail system.
Highly educative video about electric traction by power transmission through a pantograph.
nice video of pantograph
Yes Its so good...mainly the appication part of pantograph...right from the age of 5 ..we are looking railways but now I understand it is actually a pantograph mechanism.
Help Full
Nice Explanation
Thanks for the instructions.
Many modern pantographs don't have tension springs. They use an air spring that will push the pantograph up at the required pressure.
This allows to incorporate a system of tubes that will detect any damage and lower the pantograph in case of damage, preventing further damage to the overhead wires and closure of lines.
Note also that some systems use copper or metallized graphite contact strips. Those are typically high amperage DC systems.
In addition the width of the pantograph is also important, there are different standards in the world that regulate how much the overhead wire can deviate from the middle of the track (it is usually laid in zigzag and in straight sections around curves). The pantograph can't be so wide that it would exceed the loading gauge.
The horns at the end of the contact piece are important when it comes to switches where another wire "comes in" from the side. Those horns are sometimes made of insulating material (plastic) to ensure the required insulation distance to fixed objects.
Very interesting. May be you know, why double arm panthographs are seldom in Use now, mainly in trams and old trains?
@@pavelyudin8832 They are more complex, requiring more joints and space on the roof. Also more moving mass which can be a problem at high speed. So generally the simpler and more lightweight solution is preferred. Nevertheless the first generation of Italian ETR 500 was built with "double arm" pantographs which used to be preferred in Italy, perhaps offering more stability or better conductivity of high amperages? Second generation power cars were built with single-arm pantographs though.
@@uncinarynin Thank you for answer. All trains built in USSR have double arm pantographs. And sometimes they have onle one strip plank contact with wire. Working princip is simple. It is difficult for me to understand how single arm pantographs mecanism works - I mean how moving parts interact in up and dowmn moving.
@@pavelyudin8832 Usually you have two bars in the lower half ("single arm" is a simplification). They are not parallel, the two joints at the "knee" are closer together than those at the base. That means as the pantograph is raised, the upper half changes its angle and the highest point moves in approximately a vertical line (actually a lemniscate: a slight S curve).
The tension spring or air spring at the base will push up the pantograph with a certain force.
There is another bar at the upper half that will make sure the contact piece is approximately horizontal as it is raised or lowered.
It is hard to explain in words and would perhaps better need another video to show?
Also remarkable, despite their shape these pantographs work equally well in both directions. Sometimes they have little "wings" to adjust them aerodynamically and make sure the force always remains the same, even with the aerodynamic effects of high speed.
@@uncinarynin Thank you! You can find needed words to explain! Joint in "knee" of thin rod of lower arm does not change its position during arising in this video at 2:43. So it seems to me not correct and make difficult to understand working princip. So real video capture of moving pantograph is better. But I understood. Upper part of pantograph arises with higher speed but lower force. Also I found at home old drawing pantograph and played with it. If you know another video about pantograph it would be great if you share it with me. In russian textes this type (single arm) usually named half-pantograph, this termin is not strictly correct, but make it easy to define the type of mentioned mechanism. The view of single-arm pantograph seems to me more beautiful and interesting may be because of assotiations with modern trains. Also I noticed that 2-arm pantographs are not replaced with 1-arm pantographs. And do you know about tubes with compressed air in AGV train pantographs. This give protection of overhead wires in case of broken pantograph.

Good Video.Explain how is the grounding done for the locomotive. What is the type of Grounding system ?
The rails
Great animation works... Please make a video on how motor works
Sir thanks so much and please explain with electrical drawing of capacitors and transformers system rectification
Given the name and even the thumbnail I thought it was going to be about that drawing machine that lets you trace things exactly!
Great video! Well done!
When I was in France years ago, I asked one of the locomotive drivers why when going forward, the rear pantograph is used rather than the front one. He replied that the front one comes off the overhead wire at high speeds. Later I noticed that some locomotives have both the front and rear pantograph facing forward. Anyone know why this is so?
That’s because the rear pantograph faces much less air drag when compared to the front one, as the incoming air is dispersed “outwards” as it moves to the back of the loco.
@@dibendu.s Thanks for your reply. I think that you are answering the question: "why is the front pantograph not used" whereas I am asking why do some locos have both pantographs facing the same way? Normally the pantographs would face in opposite direction to one another. It would be interesting to see airflows around a pantograph at high speed. I wouldn't be surprised if some of the vortices emanating from the front pantograph (if it is used) actually strike the rear pantograph.
Please make video on switch gear and protection .
💪💪👌👌😘😘 super super video very nice I like it this video thanks for the knowledge and guide😘😘👌👌💪💪
Which tool did you used to make this video
Thanks sir
Nice explanation, but is the electric from power line is AC or DC?
And where is the ground?
Is the railway is become the ground?
Sir please give me idea about create this type of video. This type of video so amazing and creative. Please
How electric connection is established through carbon strips
Because they use graphite who is conductor while being low friction
Great video ! MUSIC LINK ?
Please make videos on e bikes
Nice make more videos about airplane systems
I still don't understand how the upper strip can stand the friction... Do they replace it often?
Super make some videos plzzz
