Cyclocross started in Europe more than one hundred years ago when cyclist were looking for a way to stay fit in winter. Cyclocross requires the power of a sprinter, the speed and endurance of a time trialist, the bike-handling skills of a mountain biker and the tactics of a road racer. It is not surprising that cyclocross has become the fastest growing part of the sport of cycling in the U.S. Events foster a festive atmosphere and encourage everyone to have fun while racing as hard as possible. Sergio, sim, funcionam como gaiolas de Faraday, ha ate uma foto famosa com Tesla sentado dentro de uma gaiola dessas e os raios caindo em volta dela toda. Os sistemas de protecao eu ja tinha levantado as hipoteses de como seriam ja ha muuuuitos posts atras, cerca de 1 ano ou mais.
Normalmente usam varistores atuando como para-raios (se quiserem detalhamento ver o link) ou os centelhadores de chifre (antigo, acho que nao se usa mais) antes dos disjuntores que alimentam as linhas de transmissao, fora isso temos a passarela que e aterrada. A estrutura metalica do carro cria uma gaiola de Faraday o que protege os passageiros, as descargas creio que sejam desviadas para a linha de transmissao tambem por um varistor dentro dos carros. Ah, outra coisa, os varistores sao de alta-tensao, veja o link que eu passei no outro post.
Varistores pelo que eu sei sao considerados como protecoes secundarias quando se tem tambem para raios, caso contrario seria primarias, ora bolas . Todas as informacoes sao corretas, trosk, e creio que serao aplicadas no carro, no entanto penso em como sera desviado o surto para a linha e dela para terra no caso de um raio atingi-lo.
A passarela entre as linhas, sobre a Anhaia sentido centro, vai deixar no chinelo qualquer Zombie-Walk ja presenciado nessa cidade. To longe de ser especialista em protecao de descargas atmosfericas como nossos amigos (e acho que meus colegas) vfbjr e trosk, e por favor me corrijam se eu estiver falando besteira, mas pelo que soube uma forma simples de entender o alcance da protecao do para-raio e imaginar um cone com a ponta nele a base num circulo no solo, cujo raio e igual a altura do chao ate a ponta do para-raio.
Sendo assim, como o monotrilho estara numa via bem alta e as avenidas por onde ele vai passar sao razoavelmente largas (fora que boa parte delas nao tem predios muito altos) o monotrilho nao devera estar sobre o cone de protecao dos mesmos, sendo assim devem ser aplicadas tecnicas de protecao proprias, como as citadas. November 6, 2015 by The Survival Mom 92 Comments When it comes to worst case scenarios, it’s hard to beat the Electromagnetic Pulse (EMP) and many people wonder how to make a Faraday cage to protect their electronic devices . I’m not ashamed to say that reading One Second After by William Forstchen scared the living daylights out of me.
Some might describe a post-EMP world as going back to the nineteenth century, but I think in some ways it would be far worse.
The simplest and cheapest way to build your own Faraday container is to use heavy duty aluminum foil. By itself, these three or four layers of foil are probably enough to protect your electronic gear, but when dealing with a TEOTWAWKI* scenario, there are no replacements, nor second chances, so it pays to do it right the first time.

For example, place your foil wrapped device into a shoe box or other cardboard box that is wrapped in foil, then place that box inside a galvanized steel trash can with a tight-fitting lid. Either plastic wrap (Saran or something similar) or plastic bags for each electronic item you want to shield. Next, wrap the object with plastic wrap or place in a plastic bag and then wrap with at least 3 layers of foil.
Place your wrapped items in the cardboard box and then wrap the entire box with two layers of foil. If you want to store large items or have numerous items to store, completely line a galvanized steel trash with cardboard.

I'm the original Survival Mom, and have been helping moms worry less and enjoy their homes and families more for 5 years. I’m sorry Lisa (not the survival-mom-lisa, the person posting above), but a Faraday cage, an old laptop, etc.
I can read the same books I had as a kid 30 years ago off my shelf, go to a collectable book store and pick up a 300 year old volume to take home, or go to a museum and look at a 2000 year old legible scroll. Existem para-raios de estado solido que posdem ser usados para desviar as sobrecorrentes induzidas na linha de alimentacao ou mesmo as desviadas do corpo do carro. Nao sei como fazem nos carros da linha 3 ou a 1, varistores ou centelhadores para o trilho? We no longer have the tools, skills, knowledge, and, in some cases, raw materials to make the most basic tools for survival. These containers are called Faraday cages and were first invented by Michael Faraday, a top-notch scientist of the mid-1800’s. A few rolls of heavy duty aluminum foil, some cardboard boxes and a galvanized steel trash can are enough to create your own Faraday cage and protect your electronics from EMP. By completely wrapping an item in several layers of foil, you can protect that item from damaging effects of EMP. Simply adding more than four layers of foil to the device is probably overkill and may not add any more protection than the initial three or four layers. For convenience, you may want to use several smaller steel cans with lids rather than just one large one. Use your hands to gently mold the foil each time, making sure there are no holes or rips in the foil. Come join me on my journey to becoming more prepared to handle everyday emergencies and worst case scenarios.

No caso do monotrilho o carro estara mais exposto e o unico desvio para terra seria a passarela de emergencia ou a propria linha de alimentacao. The novel details life in a small North Carolina town following an EMP, an electromagnetic pulse.
Keep in mind that every side of the item needs to have a minimum of three layers, so by the time you’re done wrapping it in the foil, some sides may have more than three layers. However, you can increase the effectiveness of your Faraday protection by layering, or nesting them.
With your devices protected by three layers like this, they’re likely to survive even an enhanced EMP attack with a stronger electromagnetic pulse.
If you don’t already have duplicates, make a list of what you want stored in your Faraday container and then look for inexpensive duplicates at garage and estate sales. This will add a layer that will isolate the item from the foil and will also help to keep any sharp edges or corners of the item from puncturing the aluminum foil. Be sure that no foil used to wrap the outside of the box touches any of the foil within the box.
In the event of an EMP-type scenario, it’s possible that I would be separated (long-term or permanently) from my grown children (sniffle) so I’d want to be able to pull up pics of them and look at them at any moment! In my limited experience digital formats and storage media have extremely short half-lives and are relatively unreliable. An EMP can be caused by the detonation of a large bomb, nuclear or otherwise, in the atmosphere, miles above land. This is fine, so long as you have no less than three layers of HD aluminum foil between any part of the item and the open air. Its pulse wave can easily cover a continent and destroy electronic components in computers, engines, power plants, and solar panels alike. An event like this has never happened on a large scale, and there are differing opinions as to the exact consequences, but one thing is certain: In a matter of moments, life as we know it would be gone forever.
Our closest star, the sun, could also do extensive damage in the form of a Coronal Mass Ejection (CME). The food, medications, supplies, and tools in our homes may be the only ones we have for a long time.
