That reminds me on an event which I witnessed here in germany. I lived near a small, roofed railway station with power lines. In a cold and moist winter day with drizzling a steam locomotive stopped at that station and a huge amount of black steam were caught between the roof and the powerlines and the whole station filled by that locomotive steam seemed to electrically flash/twinkle/spark obviously by the frequency of the power lines. That was an amazing view and I really asked myself if one would feel anything of that air-filled electricity if standing right in that steam...

I did a small analyse of what is happening there: Locomotives excluding from clip number 3 are export version of Škoda AC locomotives derived from Czech class 242. What probably happened in following clips is that driver intentionally put traciton in 5th degree out of 32th, which at standstill gives about 2x 1.1 kA @ 100 V per motor. This means about 450 kW (4 * 1100 * 100) drawing from 25 kV AC network. If power factor is assumed to be perfect (value 1), this means arc has current about 18 A @ 25 kV . When pantograph was lowered and arc died off, loud bang can be heard. This is probably undervoltage protection acting. If there is less than 19 kV in overhead line (25 kV locomotive, DC ones have this threshold at 2000 V) and traction is on this protection kicks in. Master switch is switched off automatically. For me is however mystery why this protection did not apply in last videoclip.

The train stopped near where I was standing and the crew had to cut that car off from the overhead power source. The arc was greenish in color and extended down until the pantograph was nearly in the lowest position, and that was only an 11kV line.

Probably sort of the same. I'm not sure why these arc as much as they do because it probably means there are circuits drawing power through the pantograph. When driving it's common practice to switch off traction, lower the pantograph and after raising it and getting a stable voltage re-applying traction. Trying that thing with traction might result in an arc, but as the vehicle is moving it might be difficult for the arc to sustain itself and get quenched rather quickly.

Germany, Switzerland, Austria, Sweden and Norway agreed to standardise on 16 2/3 Hz some 100 odd Years ago. Using precisely 16 2/3 Hz instead of e.g. 15 Hz (very early Systems in Germany) or 25 Hz (Northeast Corrdior in America) may seem a bit weird, but the Reason for that odd Number is that it helps to power the Rail System from the Main Grid, as it's 1/3 of 50 Hz. You can just use Rotary Converters with thrice as many Fields on the Mains Side (Motor) as on the Rail Side (Generator). If you're not familiar: A Rotary Converter is just a Generator driven by a Motor, used to generate AC from DC or vice versa, or to change AC Frequency as in our Example. Later AC Rail Systems use 25 kV 50 Hz, as you don't need the Frequency Equipment, the Iron Core of Transformers can be just 1/3 the Size as of 16 2/3 Hz Transformers, and the higher Voltage (16 2/3 Hz is 15 kV) needs less Copper and less Substations.

@weeardguy6 жыл бұрын
That's a Line-Insulator (allthough I have to admit that is a literal translation from the Dutch 'LeidingOnderbreker') It is used at points where two different sections of overhead wiring meet eachother. One of both ends can be grounded or even be at a different potential and to be able to have a loco drive underneath them without causing a short, this insulator is there. Most of the time it features a gap between both wires with thick metal strips shaped in a V. An arc that starts will automatically want to go up because heated air is ionised easier. Once the arc climbs to a certain point, voltage is most likely insufficient to get the arc going and it quenches. There is a video from the Netherlands where they tested this and drove under different situations (25 kv - 1500 V / 1500 V - zero) with a test-loco to see what would happen. kzbin.info/www/bejne/bGndoKaga7xrrdU

Normally, a pantograph should not be lowered under load. Try to look at it like you are powering a few washing machines or tumble dryers and you suddenly flip the switch while every machine is drawing as much current as possible. It will arc, but because the voltage is low, it won't be such a bad arc. In this case, their is clearly quite a load present, while normally trainheating, lights, airconditioning and such is powered down before lowering the pantograph, leaving lights to the batteries and heating/ventilation off, until the pantograph is raised again.

@BigHeadko6 жыл бұрын
Not really, it is common practice for example on 3kV DC line to lower the pantograph without opening the circuit braker. But the loco must draw minimal current before this (no traction current, passenger coaches powered off etc.). There are many places, where you have to lower the pantograph, so this extends lifespan of circuit breaked and reduces time of this operation. And modern machines with automatic circuit breaker switch off have problems on this kind of infrastructure cause it takes a loads of time (about 2 minutes) to accelerate after this. Also main circuit breaker lifespan is affected. But in this particular case, it is on 25kV AC power line, and there you really must open main circuit breaker before lowering pantograph because of the magnetization current of the transformer.

+Brent Boswell - The lower frequency is technical based at the power station generators, because there is a special circuit of the coils, which make it possible to get 50Hz for the normal electric network and 16.667Hz for the railroad. I think, it is the voltage because in Germany we have a 15kV railroad net. Other railroads use 20kV or 26kV with 50/60Hz. Higher voltage is more able to make an lightning arc.
@Engineer97367 жыл бұрын
I heard from another KZbin video many years ago that they use that frequency because old DC train motors can run on that with not too much problems.
@TC-Rail7 жыл бұрын
Yes, that is the real reason. At low frequency, the DC motors can run on AC and there is no need of onboard rectifier, which was a problem at the time when the railroad electrification in Germany occured. At 15 kV you have the benefits of higher voltage without rectifiers but you have to use havier transformers. The arc also have less stability at low frequency and voltage. The 16 2/3 Hz is exact 1/3 of 50 Hz which makes converting possible with one common converter or motor and generator on one common shaft. With removal of all the rotary converters, some countries changed to 16.7 Hz. Most of the other countries with early electrification decided to use DC with stationary rectifiers or AC-DC rotary converters.

@Kromaatikse6 жыл бұрын
On DC electrified lines, it is common to raise both pantographs if fitted, to reduce line contact resistance. There are no phase changes at neutral sections to worry about in that case. DC is typically at 700-3000V depending on the line, so the insulators are quite small. On AC electrified lines, raising both pantographs simultaneously is a Big No, because the two will straddle any neutral section and form a short-circuit between the two power phases supplying different sections of the route. Normally the one further from the leading cab is raised, and the other lowered. AC is typically at 12-25kV, so the insulators are relatively large. An arc-quenching circuit breaker is normally fitted in line with the pantograph, and is automatically opened before the pantograph lowers. Bulgaria is one of several countries using 25kV 50Hz AC. Finland and the UK also use that standard; some British electric locos (ex Class 87) now run in Bulgaria.

Normally this is not possible, because you should not be able to lower the panthograph as long as the train drives has not cut the power internally. If this is impossible due to a technical issue, the best solution is to cut the power to the catenary before lowering the pantograph. However many train drivers and maintenance technicians don't do this and this causes damage to the catenary. I suppose (I hope) these are just tests.
