Section insulator arcing and short circuit caused by faulty pantograph

I was triyng to capture the pantograph passing some insulators at high speed. The weather was bad and the video wasn't succesful but I catched both the unnoticed faulty guide rod and the short circuit caused by it when I tried to test the other pantograph.
Note how the pantograph "walks" from side to side across the contact wire as the unit moves down the way. This action is achieved deliberately by displacement of the wire from centerline when it is installed, to promote uniform wear of pantograph heads.
Actually, it works the other way around - the wire sweeps across the pantograph contact bar, by anywhere from 200 mm to 400 mm either side of the track centerline - a parameter called stagger.
And for work for longer
@@smwca123 thats literally what he said
that pantograph is like " NO NO NO I DON'T WANT TO TOUCH THE WIRE MOMMY"
🤣🤣🤣

I like how it gets back up after getting beat down
Hahhahaha

Uhh... Why do you think is it lowering? I dont think it can go straight through the line, bruh.

The Romanian Railway has specific orders on faulty pantographs, the main switch (disjunctor has to be disconnected and the faulty pantograph must be isolated). The fact that both the pantographs were enabled (A+B active) and the front one was raised led the 27 kV to energise the malfunctioned pantograph and its loose piece to arc with its action piston or the metallic top cover. The order states clearly to switch off the disjunctor, get down the faulty pantograph (if possible)and then stop the train, inspect the possibility of isolating and lowering it or leave it as low as possible in order not to interfere with the catenary. If not possible, the locomotive is claimed as a major disfunction. If not, in the machine room enable just the front pantograph and start the train again for the first station where the locomotive should be declaired unablr to continue. The electric arc will eventualy distroy the pantograph and melt the catenary wire.
Slow down there buckaroo
@@youngeshmoney It's because of the job, if you don't mind.
O explicație completă și la subiect!
The contact wire, not the catenary.
Cool descent of pantograph. It's a Romanian built EA 060 locomotive. Operating on Bulgarian Railways. Great work !
It’s amazing there is enough of a electrical contact to make a train move like that ..
At 27,000 volts, it doesn't take much current to pull the train. A typical locomotive rated at 1500 HP (1119 kilowatts) will draw only 41.4 amperes at full power. At typical cruise power, the current draw will be roughly one quarter of that or 10-15 amperes.
Frank Roberts are you sure 1100kW loco is a typical one? Even 30 years old ones have often max output of over 3000 kW. Modern locos mostly have around 6400 kW, Taurus can give you even over 8000 kW. All these are outputs, so the actual power drain will exceed those numbers.
@@frankroberts9320 you should have awarded Darwin prize for this nonsense comment. Lol.
@@Hot_guy267 The irony is strong in this one.
@@frankroberts9320 the same u proved correct for urself again. Man grow up.
I feel this pantograph. Been through hell yet I still get back up
Nice catch! Interesting to see how they work. I thought pantographs were isolated from each other?
You say the weather was bad but that's a fantastic backdrop with the cloud cover and sun!
Each pantograph can be disconnected from the main circuit if needed. In this particular case the fault do not prevent the pantograph of working normally, but cause a short circuit if only the other one is rised. I have disconnected the faulty pantograph for the returning trip.
Also if both pentos are up and you go into a neural section. The substation will trip out.

It's actually amazing how they don't really arc more than that, must have really smooth contact in normal operation. What kind of voltages are being dealt with here? I imagine it's in the thousands of volts?
cuz the motors are in action thats why it is not arcing more that that
It is typically 12KV, but not many amps. It is the amps that count for the bang.
why did the explosion at :51 make me laugh and make me think like the panto was farting? LMAO
Look at this pantograph, Everytime I do it arcs like that
Wait, where is the piston that keeps the panto on?
Just thinking about the cameraman😂😂
0:50 Power over 60km of electrified track just went out
change in voltage can cause spark
Sounded like a 25-Hz buzz maybe? Heard it for only a brief moment but that's how it sounded. At one time, 25-Hz AC was in common use with electric railways and trams.
50 Hz.
@@TC-Rail It is 50? Thanks. It was difficult to tell from the brief spark.
I want to know why both the pantos are up?
What is wrong with this thing?😮
How exactly is this a short circuit?
Good capturing brother 😉
Cameraman again survived -_-
The pantograph is going up and down caused the contact wire & section insulator abnormal arcing and wearing.
Very Nice video! greetings from Poland! ;)
Nice shot
But my question is,Who in the World, Will Put His Fricking Camera on The Train Engine Roof? Doesn't Make Any Sense To Me, Not Even a little bit.?
Great Video 😎👍
Camera management on the roof😱😱
Sad... The train couldn't cross those clouds.
😂😂
It arced through the metal body of the train. I was expecting to see a flash and hear a bang, though.
How did u shut...excellent
Why does the Pantagraph go up and down like that?
Should the back be turned on When going ahead brother
Who put the camera up there
That lazy poor phantograph
¿ Para que bajan tanto la catenaria ?
What is that long thing dangling back and forth at the left side under the support arms?
I reckon that is earth tape. When the pantograph at the lower down position, the earth tape tauching the train roof then the pantograph was earthed.
@@dfuhbvjcf5090
Earth tape? What?
That long piece is the release valve if I'm not mistaken.
It releases the air that makes the pantograph rise and fall.
@@blue9multimediagroup Thanks for the info. My trade is Overhead Line.
@@dfuhbvjcf5090
Granted it does look broken cuz it's not supposed to hang down like that.
What country was this?

If the train is in service and this one happens, emergency brake should have been applied and the train should have stopped service immediately
Why? Isolate faulty one and carry on, no extra delays needed...
That's why they have 2 pans. You lower one and raise the other. No biggie.
@@blue9multimediagroup The French class BB15000 has only one pan each; SNCF apparently decided that's all they need.
I saw the pantograph running lower at 0.44 to 0.50. I reckon the contact wire height is lower caused the pantograph (briefing). Was there the gradient 1:300 or 1:400?
sigil... Low hight of contact wire is thro' under bridge only. How come in here too?
Im kind id lost. What happened and why?
The train driver has noticed the faulty pantograph and has tried to lower it down. Since both pantographs are connected and because of the broken/hanging part, the current from the first pantograph short-circuited the lowering mechanism of the pantograph. Because of the way pantographs work, the springs pushed the pantograph up to the catenary again. Since the current from the catenary connected through the loco to the return line (rails) it short-circuited the whole section between two insulators (of which one you can see at the beginning).
Big like....Great work...Thumbs UP!!!

Ok my mistake. I was confused because of AŽD 70 signals, but I found it on your another video. Its really strange modification.

In America we don't build full scale electric model trains, we use diesel like real men.
Ha. Hope you like your 60mph diesel locomotives! If you don’t mind, here in Europe we will operate at 200mph with our ‘full scale electric model trains’.
