@NSaw1 Год назад

@@thinklist It also has to do with the surface of an insulating material, I have experimented with it and also recently I saw a video about it, but I can't find it now. So basically if you have a solid insulator and two wires 2cm apart inside the insulator, it can insulate the two from each other at a given voltage. But if you where to have the same type of insulation but have a clean, dry surface between the two wires it will jump across the surface of the insulator at a much lower voltage than even that if there where just air between the wires. So the surface of an insulator has a lower resistance than a solid insulator, which is another reason why even standoff insulators that are indoors will have some ribbing. I wish I could find the video, it was very interesting.

@Lucien86 Год назад

@@thinklist Everything said is no doubt true but there are more basic reasons for the ribbing - disk structure. - It provides a large maximum centre to outer insulation distance for minimum material. - In insulators made of ceramic it also provides a much better more stable shape that is less likely to shatter or explode during firing. - The third reason I know is that for insulators outside in the rain the ribs create a series of air gaps that are better able to avoid continuous water surfaces forming. The gap disk structure is also good at breaking any plasma arcs that result if a water link does form. Also at resisting the shock of small explosions.

Even through the 185mm cable is only rated for around 400amps, he is counting on the duration of the surge of current being so short that it won’t have enough time to melt and vaporize the conductors. The energy transfer here is also extremely crazy if we use the capacitor energy storage formula: E= 1/2 * C * V^2 where c is the capacitance in farads, v is the the voltage, and e is the energy the capacitor stores in Jules. And by using this formula we can determine that the capacitor bank is releasing 45,000 Jules of energy in under a second which is totally insane! Anyway excellent way of explaining what’s going on for the folks who are not sparkies or electrical engineers

Another good thing to check would be to estimate the resistance of the setup. Those cables in parallel for the ~6 meters (3m there and back) is about 0.06 mohm/m or about 0.4 mohm. It's hard to be sure what the rest of the setup resistance is, but let's use 1 mohm as a guess. He said 3kV was the capacitor voltage. 3kV/1mohm = 3MA. His goal of 200kA was probably reached. It also shows the 185mm cables were more than enough to handle delivering that current without much loss. If we assume 200kA through 1 mohm, that is a V=IxR = 200V drop, leaving 2.8kV left for the fuse. It is really too bad we don't see him use tools like a mohm meter on the setup, or a scope (with divider) to see the current or voltage curve hitting this thing, but it does blow up fairly quickly, so he probably got quite close to his 200kA goal. The reason he probably needed 3 runs to fully break it was the current was applied for too short of a time.

@foogod4237 Год назад

The trick with the power cables is that those ratings are assuming continuous power draw over an extended period. For this application, the current is only going to exist for a brief fraction of a second, and so the total heating of the cable will be much lower, and thus you can pump a whole lot more current through it, as long as it's only for a very short time. They still might not last forever, though, if you reuse them enough times...

@johncoops6897 8 месяцев назад

The current rating isn't even based on that... it's related to the amount of (acceptable) voltage drop over the cable run. The amount of current is consistent at all parts of the circuit, so providing there is some voltage available, there will be the same amount of current at the load (a poppable fuse in this case) as started out at the source (capacitor bank).

I'd have to say photon is amazing. He's done a lot of awesome stuff. Many demonstrations and experiments. He's a very intelligent man who does all the things you should never try at home so you can see it without having to try it yourself. Don't get me when, I'm familiar with installing light switches, outlets, switched outlets ceiling fans and the like. I know what I'm doing when it comes to stuff like that. I would never mess with anything over 240 volts and definitely not capacitors charged with thousands of volts. Microwave transformers can put out 5000 volts and the charged capacitor inside is something I wouldn't play with. I know my limits and won't do something dangerous. He's an electrical engineer and knows a lot more about not making mistakes than a do it yourselfer working with basic conduit. I like in the USA so we run on split phase. We do have 240 volts between phase 1 and 2 hots, but most of the plug receptacles and light fixtures run on a single phase to neutral. Only the big appliances like the dryer, electric stove, water heater, and the central heat pump for the whole house HVAC run on the full 240 volts. Everything else run on 120. Anyway we should all appreciate photon for doing the things we should never try unless suicide is the goal.

The ribs on the insulators are for making it harder for tracking to happen. A spark will just jump across and take the shortest path - tracking will have to follow the surface.

In the UK we call this, creepage. The disks on the insulator increase this creepage distance. Creepage is especially affected by the environment.

@markgrassl4449 5 месяцев назад

7:15 The ribs on the insolators are there so water wouldn't form a continous film around the insulator, shorting it out. Thats als why most of the time the outline of the ribs go down-out and back in-up (umbrella shapes) so water would drip off at the lowest point and not wet the bottom surface so the bottom side of each rib would stay dry even trough rain.

@schrodingerscat1863 Год назад

The sheds on high voltage insulators are to increase the surface area between the conductor and what ever it is being insulated from. This is because when the insulators get wet you get high voltages creeping along the surface of the insulator and so you want a longer distance on the surface of the insulator as the insulating properties are reduced by atmospheric conditions.

We used to suspend a screw driver in the air in the magnetic field.

@LeoH3L1 9 месяцев назад

Regarding the HV line insulators, the shape of them isn't to prevent jumping, the gap does that, it's for another thing called "creepage". There's two concepts at play there, there's what's called creepage and clearance. There's two ways that current can "jump" a gap, a jump strictly speaking is via an arc through the air, which is where the clearance is the primary insulating factor, but it can also creep along a non conductive surface, this isn't so much a "jump", as it is along a surface, by having those "ribs" you increase the distance along that surface to the point where it is too far for it to creep across it. You can achieve sufficient clearance, but still have problems with creepage if you don't design it properly, and creepage can be massively effected by for example water, so by shaping those insulators like that, they act like their own little stack of umbrellas, the underside being kept dry, and keeping enough dry surface to prevent creepage even if it has been raining. So it's a clever design that both increases the surface distance between the conductor and the pylon, and provides protection from water wetting the undersides of each section. The distances invoved in creepage and clearance are very dependent on the voltage and the physical conditions, eg moisture content of the air, surface dryness, surface finish, surface contamination, which water on it would be. Also if there is a conformal coating that has an effect too, as the current could instead go through that rather than run along the now covered surface, adding a conformal coating could actually in some cases make things worse than leaving it exposed. The design of things with creepage and clearance in mind can get very very involved, and that's just what I've picked up from looking into it for work and working with people who deal with this day in day out. I wish I could post a pic on here, but if you search for "creepage and clearance" there's a great picture of such an insulator where someone has drawn on it the creepage and clearance paths (even though they've spelt creepage wrong) and it shows that the design of these drastically increases the creepage distance. I will post the link as a reply to this, but I think that thinkLIST will have to approve it for it to be visible.

@nobody.of.importance 9 месяцев назад

7:16 Just spent about half an hour researching this and it looks like your description is spot on. Fine details are as follows: Insulators such as those pictured can break down typically in one of two ways: a puncture arc and a flashover arc. Puncture arcs quite literally burn through the material, leaving the insulator damaged. Flashover arcs, on the other hand, are when the electricity takes a path AROUND the insulator (as demonstrated), leaving the insulator more or less unharmed. Insulators as such are designed so that flashover arcs occur at lower voltages than puncture arcs. Additionally, being out in the elements pretty much at all times, they have to be able to handle contaminants on the surface, such as dust, soot, or even water. As such, they're designed so that it maximizes the distance the electricity has to flow across the surface *through* those contaminants. Additionally, a lot of them have an upside down saucer shape to prevent said contaminants from building up on the underside, further making a complete circuit around the insulator less likely. Obviously I'm not a professional, but it's still a pretty neat topic. Never thought such a simple thing would have so much effort put into it, eh?

@DavidStruveDesigns 2 месяца назад

Part of the reason for insulator design is yes to provide more surface area the current needs to defeat to complete the circuit, but it's also to push that potential arc outwards so that it is forced outside of any magnetic field created between the two attached cables which would make it easier for arcing current to flow through (sort of like it's own invisible cable made up of a magnetic field "tube") as WELL as designed that way with the flare at the bottom (along with various geometry added around the lowest lip) to try and prevent water from rainfall from dripping down in a single stream from one cable end to the other that could cause a short to flow through it. The rain is essentially pushed outwards and made to drip rather than flow, so that there's no way it flows down close to the bottom connection point. I watched a video here on YT that went through the history of insulator disc designs and how they changed over time - their overall shape, the length of the entire set of insulators, how many are used etc. It was rather a fascinating look into something almost none of us ever think about that does such an important job!

Re insulator shapes: 1, as you said, to increase the creep distance.

In the UK we have the IET Wiring Regulations that are a British standard. Bs767. It has very similar charts to the ones you showed. For the short run and duration of use I'd not worry about the trunking/ conduit. I'd say the conduit was to protect the cable insulation as it tensed.

@IanTaig 2 месяца назад

Just a comment on the insulators, the reason they are shaped that way is for 2 reasons, the first is to drastically increase the creepage distance to reduce the how likely there will be surface tracking, the other reason is when they are out in the open, it would be incredibly hard to get all of the surface wet because of their shape, so you will get tracking on the wet surfaces but not as much on the dry. If you have been near a tower that is 220kV or higher after rain, you can hear them buzzing, that is tracking across the insulator surface which happens when pollutants contaminate the surface and get wet.

To be a bit more precise, the ribs on insulators are there mostly for water. If it's enclosed, then it can be just a ceramic tube but if it's outside, a bit of water on the surface will be enough for high voltage to jump over it. Those ribs don't let the water to create low resistance path on the surface. That's also why there is different design depending on the orientation of the insulator.

The ribs are against ice forming. In cases where you have ice rain, the underpass prevents a continious icesheet from forming, thus, preventing arching or short to earth. The Increase of surface is a nice bonus.

@obsgr1 Год назад

HV insulators are ribbed for both more surface area and to reduce water droplets from creating a shorter path. The more you have and the bigger they are the larger the voltage and amps can go through. Where they are used, eg. in salt air environments or in the plains, and the material they're made from, eg. glass, ceramic, composite, can also affect the flashover current.

Photon's always been a fave of mine whenever he's managed to upload. Seeing ElectroBOOM etc. on here too, very excited to go through these. Although I think I might have spoiled the rest with this one 🤣 I'd love to see more Photon vids among the rest, if you've not already got them!

The look-up table you have for cable current is already quite heavily derated - and extremely conservative. If you look at other tables such as "SAE AS50881 - Wiring Aerospace Vehicle specification" you will find that a 4/0 AWG (120mm2) cable is rated for approximately 1000 Amps continuous load (un-bundled with a PTFE/ETFE sheath & aramid jacket @ 1ATM). For a microsecond pulse like this, the cables can easily handle orders of magnitude more current that that.

The ridges are indeed for increasing the distance, and to stop the possibility of dirt being capable of providing a route over which an arc can travel easier. My dad always explained it to me when I was a child like this: "Voltage like short routes, it doesn't want to "hop" from point to point, so all those discs and their ribs make it much more difficult for voltage to jump from point to point."

Late to the party. My career was with the big American telephone system. Among other things, I maintained the power room for the electro-mechanical switches in New York City and as an international gateway. It ran on batteries that were always floated to keep them charged. half a square block of five foot tall 2 volt lead-acid cells in strings to give 48 volts at gizallian (?) amps. They were all connected by thick copper plates that ran to more copper plate buss bars. An associate was doing something with a 1/2 inch ratchet, and you know what happened. He was stunned but the wrench disappeared. Only small pieces at the ends were still intact. The entire handle vanished. Thanks for the recollection.

Allen Bradley has a high current test facility in Milwaukee, Wisconsin, USA. A 50 HP motor drives a big flywheel low voltage generator (about 10 meters in diameter), Basically you spin up the generator, declutch the motor as you close air switches to the load causing the freewheeling generator to dynamically brake with the bolted fault. There is an air core transformer to select various voltages and currents. All cables and bus bars are supported by wood to avoid inducing unwanted currents . UL, IEC & NEMA testing certified.

PhotonicInduction is a pure legend when it comes to destroying electronics. I love watching his videos. If I recall correctly, though I may be wrong, in one of his videos he was showing off a hydrogen reactor he has to power his equipment and capacitor bank.

WHAT a hydrogen reactor. That is mental

When considering insulation you must consider creepage and clearance. Creepage is the shortest distance over a surface between two conductors and clearance is the shortest distance trough air between two conductors. The ribs just increase the creepage distance.

I worked for a company that that had work place feed with a 4Mwatt transformer. 72kvolts primary fused at 60 amps, 600 volts secondary. With 6000 amp fusing 200 feet away from transform. Feed from the transformer was stacked bus bars unfused. 1) first event we had 6000 amp main breaker blow because of MCC cells fusing uncorwardaided fusing. IE one cell was 1600 amps. We had x6cells =9600 amps. Normal current draw was about 4000 amps, but when we got a short circuit on one of cell feeder cables, it tripped main 6000 amp breaker. Contacts were all arced out. 2) then a while later we had the bus bar short out. They assumed a hot junction, as these bus bars were clamped to join, not a bolted connection. A joint every 8 feet. Not a good design. A person was walking about 50 feet away, almost shit his pants. The primary fuse blew. And the clamping bolts were torque to yield, so no way to come back later to retorque the clamp bolts. Maybe joint expanded from #1 trip. But we lost 3 weeks of power from that transformer waiting for bus bars. I would go with multiple single conductors. At least you only have 2 end bolts to torque. Instead of 60 plus clamp bolts. 3) even 12 Volts DC, with enough amperage can kill you. I was trying to jump start a wheel grapple loader. There were 2 D31 batteries on machine, but not enough voltage to spin engine, then i hooked another d31, and finally a 200 amp battery charger. Well over 1000 amps, enough to weld the start contacts together. I knew batteries were getting hot so i reached down to remove one of the jumper cables, when the batteries blew up due to hydrogen build up. I had an arc in a box, with nice battery acid coming at me. Good thing i wore my PPE. I am here today.

@davidwallis4567 8 месяцев назад

The undulating design of the insulators is to increase the creepage distance across the surface of the insulator for the given distance between the conductors. E.g. if you have a distance X between the conductors by castlating the insulator you can make the surface distance across the insulator 5X. The reason why this matters is because the electrical energy will track across the insulator surface much easier than if it was free space between the conductor. A longer path across the insulator surface gives a larger insulation voltage between the two conductors.

@zerumsum1640 Год назад

I've always heard it as the ribs on insulators are there so rain/water doesn't have a chance to create a path for the power back to the pole. i can see that being a concern in power transmission, as for here it may have something to do with making sure the path that the electricity would have to take if it is following the surface of the insulator far longer than if it was just a solid piece.

@thinklist Год назад

I think 🤔 you’re spot on

@davidmcdonald3314 Год назад

The multiple ribs / plates in big insulators would, I believe, also separate each disc from those beside it and should provide multiple spark gaps that would need to be overcome - so there is multiple layers of redundancy against bridging the gaps by ingress if dirt, water, etcetera

@markgohl2660 9 месяцев назад

I think the ribbing is on the underside of a high voltage insulator is to increase the distance a surface current would have to travel to escape and also to function as a drip point for any rain

The ripples on the insulator/feedthrough/standoff are for electric field manipulation. A sinusoidal or parabolic pattern (revolved around the cable/current axis) takes advantage of electric field lines' tendency to follow the shape of the medium; the density of equipotential lines (voltage essentially) maximizes at the sharpest points for the same reason. A smooth, uneven pattern "squeezes" the radial potential gradient coming off the conductor as the dielectric thickness increases. The smooth slope and evenly space local maxima of a sinusoidal pattern increases the axial distance between points as the potential gradient increases as well (c.f. a step fuction shape which would have two sharp corners at each local maximum which are not optimally spaced from the next local maximum). The points with more potential energy are further apart and have the most protection due to design and simple geometries! This reduces material costs and can aid in design of directed dielectric breakdown.

@Nanocosm 8 месяцев назад

I have no experience with HV but the shape of the insulators is there to increase the creepage distance. The clearance cones from their length but the creepage path is much longer so the current has to track over a longer wet surface. Also it looks like large parts od that path could be kept dry by the shape. Everyone whos interested, google clearance and creepage.

@inothome 8 месяцев назад

Bells or sheds on insulators.... That's for the "creep" distance and yes, the current would have to flow further to cause a flash over. The straight line measurement is called "strike". Each bell on an old porcelain type is usually rated for 10kV. So you can get a rough idea of the line potential by counting bells. Poly or single piece insulators are a little different and there's no way of counting sheds to determine the insulation class. You just go by looking at it's length to determine what kV rating it is. And the short circuit fault current a wire or cable can handle is much more than the rated ampacity listed. We use 4/0 protective grounds for grounding (earthing) and I think they are rated for 20,000A fault current but only for 15 cycles or so. Which is much longer than any protective device should operate in, usually 5 cycles or so. I forget the actual ampacity / cycles, but it's much higher for momentary faults, for any wire or cable. As he was doing in that video.

In the netherlands the default trip value is B, when requested you can get higher for for example the garage if you run higher starting current devices but it is an option not standard. I needed them as well when I bought my 2.2kw 230mm angle grinder. it has no soft start so the peak current was way too high for the fuse (schakelautomaat in dutch is translated to automatic switch I assume this is not correct?) My new workshop has 400v 35A main connection that branches out to a couple 400v outlets, a couple 230v C24 and the rest 230v B16 as is common for domestic appliances (such as my computer, audioset etc. I saw photon's video's first about 8 years ago, interesting for sure! Good to see he's back, he stopped uploading for a couple years. (now that I think of it, my last video is also more than 3 years ago, about time for something new!)

Current capacity of a conductor is largely a factor of time. Those books all are for safety and continuous use and temperature rise, for a pulse you can do way way more. Magnetic fields will cause cables to move, I've seen a 1500A breaker tested and wires moved around a lot

@LeoH3L1 9 месяцев назад

HRC fuses stand for High Rupture Capacity, not High Rupture Current, the "Capacity" refering to its capacity to contain the energy that would be released when it blows, what it means is it can contain the explosion of material that is going on inside it.
