Do you know which country has the highest annual incidence of lightning strikes in the world? The answer to your question is simple, we are talking about Brazil. The number of lightning strikes here is so great that several myths have been created over the years about these electrical discharges. In today’s article we will talk about the myths and truths about lightning.
What are the rays?
The lightning is an atmospheric electrical discharge that crosses the sky in search of an opposite charge with a great force that can cause several damages and / or accidents.
What are the biggest myths about lightning?
Lightning never falls twice in the same place
- One of the most passed on information in history is also the biggest myth surrounding this subject. During the storm, the lightning will most often look for the form with the least resistance to reach the earth, that is, the pointed, elevated structures and especially the metallic ones are the ones that are more likely to receive lightning strikes. Therefore, a very tall building, or a tree in a field, can be reached several times a year. Another important detail is that the same ray can be multiple, that is, it can occur several times in very small intervals, which gives the impression that when a ray falls it blinks, what actually happens is that the ray did not dissipate all his load and he repeats the descent once or several times, multiple rays have been recorded with 28 subsequent discharges.
Only the rays burn the electronic devices
- This is incomplete information and that is why it is in the myths! The truth is that electrical surges are the biggest cause of appliance burns. These surges can be caused either by lightning or by sudden variations in network voltage.
Am I protected inside the house?
- Undoubtedly, being indoors is a great way to protect yourself from lightning strikes, but that does not mean that you are fully protected. When a person does not maintain an ideal distance from electronic devices, electrical cables or any metal material, the chances of a person being shocked are enormous.
Does the stabilizer protect devices from lightning?
- The name itself says, the device is a stabilized one and its function is only to protect the devices from the variation of the mains voltage. To protect the devices from lightning, it is necessary to use a DPS. (Electrical surge protection devices)
Do surge arresters protect electronic equipment?
- The answer is no! They have the function of protecting only the construction, in other words, to protect your electronic equipment, it is necessary to install a voltage surge suppressor that has the function of preventing electrical discharges reaching the devices by burning them.
Do the rays always strike the tallest object?
- This is another myth that is widely shared as true information. Taller objects are more likely to be hit by lightning, but this does not prevent lightning from hitting the ground or even shorter objects that are close to larger ones.
Tents and trees are good shelters
- If you are well aware of all the information that has been passed on here, you certainly already know why this statement is false. When a person is outdoors during a lightning storm, he should never take shelter in a tent or under isolated trees. Both the trees and the metal shafts of the tents will attract electrical discharges.
What are the greatest truths about lightning?
Never talk on the phone during storms
- The person who does not respect this indication will certainly be taking many risks. Lightning can cause electrical surges that easily pass through the electrical network, the telephone network, and also television. If a person is holding the phone, they can be hit by discharge.
Should I unplug the appliances?
- Lightning surges in electrical networks are extremely dangerous for appliances. This attitude is highly recommended, even in installations that have lightning protection.
Is the temperature of the lightning higher than that of the solar surface?
- This is practically a curiosity! The information is true, the solar surface has approximately 6,000ºC since the ray can reach approximately 30,000ºC, that is, the temperature of a ray can be up to 5 times higher.
Is it possible to calculate the distance of lightning by the time that the thunder?
- The answer is yes! If you don’t know, the speed of sound is approximately 1 kilometer every three seconds. So, as soon as you see the lightning, you can count the time it took us to hear your thunder. To exemplify, imagine that it took 10 seconds to be heard, in this case, the lightning is about 3km away.
To end this article, we bring you some important tips to help you when protecting yourself from lightning storms. See how some places can be much more dangerous than safe.
How to stay safe in a lightning storm?
- Find shelter in buildings
- Avoid kiosks and tents
- Avoid taking shelter near trees
- Avoid staying in pools, rivers, lakes and / or the sea
- Keep away from metallic objects such as poles, masts, railings, fences, and fences
- Avoid high, isolated locations
- Avoid staying on boats, boats or rafts
- Avoid using landlines, except for wireless and cell phones, but still use them only in case of emergencies
- Never plant trees close to places close to where flammable and / or explosive products are stored.
