MASSIVE DESTRUCTION (not really lol). A power line just randomly fell on our street causing some damage, no one was hurt. Thanks to the William Penn firemen, Middletown Township police and local PECO unit.

Schematic: img81.imageshack.us T300-52 iron powder toroid, wound with 50 turns #24 AWG closely together on the primary, and 600 turns of #30 AWG on secondary. Input is a 4.1 kHz square wave from an IRF740 MOSFET connected to ~12 Volt power supply, 50% duty cycle. It's a pulsed DC entering the primary. Since the square wave is DC during the mark phase, and DC goes easily through an inductor, there was quite a bit of current being sucked through even though no load was on the secondary. Nevertheless, as you can see, even with a 1:12 stepup ratio (as would be the case with a sinusoidal input), the square wave resulted in what looks like 3-5 kV from the secondary. With a real load (like a water cell) this would drastically drop, but interesting to see 12 volts turn into a several kilovolts with a mere 600 turns on an iron powder toroid. It's a flyback effect, but I'm not sure how this hand-wound toroid stacks up against a commercial flyback transformer. Once you have a higher voltage signal, then you'd probably need an impedance matching or bridging network between it and the water cell, or perhaps a pulse-forming network to sharpen the spikes and crack the water that way...

2 year old GE Microwave oven JE1860BH04 with the magnetron causing arcing and burning. Can see red hot spot a few times, best at about 55 second. Magnetron WB27X10305 Found the magnetron antenna cap with hole burnt/melted. Hum... about an hour later, my hand feels kinda strange. DOAH !
This video taken with the panel totally removed from service -- DO NOT ATTEMPT WORK ON AN EXPOSED PANEL UNLESS YOU ARE QUALIFIED TO DO SO - YOU COULD BE ELECTROCUTED AND DIE. This Westinghouse circuit breaker panel was installed in a new home in 1993. In July 2011, it had a failure of the busbar contact with three circuit breakers. This caused a burning plastic smell and the warming of the area where the problem occurred. The electrician said he saw problems like this about once a week and that I had to replace the entire panel. He did not single out this brand as a problem. The cost to replace the panel itself loaded with new breakers and to pay the city electrical permit was $900. The city pulled the electric meter so this work could be done. Westinghouse sold the panel making business and it is now owned by Eaton Corp. Eaton says " There is no recurring problem with this product. Occassionally we get requests for replacement breakers or covers for the old Westinghouse loadcenters, but I've very rarely heard of any problems with them. Also, there is no program in place for reimbursement for repair costs." If you have had a problem with a "Westinghouse" circuit breaker panel made around 1993, please post a comment here. There were a rash of problems years ago with panels made by a different manufacturer.

A request from user MrTurboTurbine, a high speed video recording of arcing on a motor commutator. The arcs are not pulled from the brush, they in fact are confined to the gaps between the comm bars.

These CFL lamps had done their service. The Philips clocked over 20000 hours. I used a 2kV MOT first, which overheated. Then a 480 Volts TX to burn out the internal wiring.

While sitting at 181st Street, a downtown 1 Train comes in. When leaving, the third-rail shoes put on a performance that would put the Macy's 4th of July fireworks show to shame. If you have any questions about the video, feel free to message me. Comments are welcome. The video was taken on July 30th, 2008.

Situation: After making his previous 11 free throws, Dirk Nowitzki gets to the line for another two. He carelessly misses the first and is taunted by the opposing crowd. He responds by raising the degree of difficulty of his second try, taking a very high arcing shot that hits nothing but the bottom of the net for his 43rd point of the game.

This video shows the principles behind metatarsal doming or arcing exercises for foot strength. Every day we are in shoes our feet weaken. Every day we are in orthotics our feet weaken. Every day our feet hurt they weaken. Foot strengthening should be a major goal for all people.

Audio: Sound of arcing from between (phase) wire and upper contact on a fuse/disconnect assembly. The RF effects of this 'arcing' could be received over a _mile_ away on a Sears portable AM/FM/SW radio Model 2278 tuned to 2.6 MHz as demonstrated on this video: www.youtube.com The arcing noise could also be heard on a car radio tuned to a quiet AM channel like 1610 or 1650 kHz over a mile way. When driving by this pole on McDermott the 'arcing' would override 570/KLIF and 820/WBAP, and was noticable on 1080/KRLD. This problem was fixed by Oncor 4-26-2008. .

tied with the insane t-storm videos. As the heart of the storm settles in, a very large tree limb or possibly a lightning strike hit an electrical line and/or transformer, causing it to short out. The first blow was VERY quick, intense, and loud. Power trips at substation right away. The power remains tripped for about 2 minutes, before it re-routes back, and the powerline begins 30 seconds of loud, high voltage arcing. Power surges occur during the time of arcing. Soon, the line finally snaps from all the super heated arcs, and 1000+ people in Lincoln go dark. The last customers were restored about 9 hours later. Some got theirs back within an hour, but my grandma's house (where this was recorded) did not get it back till about 1:30 AM

Arcing loops above an active region put on a slinky-like show for SDO, evidence of the dynamic, magnetic struggles taking place below (Nov. 28-30, 2010). Particles spiraling along magnetic field lines trace their paths as they gracefully shift and change. Magnetic forces in the active region are connecting, breaking apart, and reconnecting. Another active region that rotates into view about halfway through the video clip exhibits similar behavior. These frames were taken in extreme ultraviolet light. The smooth motion of the video is made possible by using an image every five minutes (which is just one out of every 60 images taken in five minutes by SDO in this wavelength). Credit: NASA SDO

This was an electrical fire we had at our old house back in 2005. We had to wait for FPL (Florida Power and Light) to disconnect the transformer to out house before the FD could work on putting the fire out. The jumps in the video are because I spliced 3 short, separate clips together.

Some high power arcs with a HV transformer wound on the core of a TV diode split transformer, with ~750 turns of 0.3mm wire. The transformer is driven by a ZVS driver. It draws more than 30 amps at 39 volts (above 1200 watts...). I suggest the output power to be around 1kW. The secondary of the transformer has an ohmic resistanc of only 13 ohms. A diode split transformer of a TV has about 3000 ohms. After this arcing, the transformer was just warm (about 40°C). A DST would have been destroyed after a couple of seconds.
