Les principales raisons sont les surcharges \u00e9lectriques, les c\u00e2blages d\u00e9fectueux, les coups de foudre et le r\u00e9tablissement du courant apr\u00e8s une panne de courant ou une panne de courant.\r\n\r\n<strong>Surcharge \u00e9lectrique<\/strong>\r\n\r\nDes surcharges \u00e9lectriques peuvent se produire lorsque trop d\u2019\u00e9nergie est consomm\u00e9e sur un seul circuit. Cela se produit le plus souvent en raison d\u2019une utilisation excessive des rallonges et du branchement de trop d\u2019appareils sur le m\u00eame circuit.\r\n\r\n<strong>C\u00e2blage d\u00e9fectueux<\/strong>\r\n\r\nUn c\u00e2blage d\u00e9fectueux est une cause interne potentielle de surtensions, qui sont plus susceptibles de se produire avec des fils \u00e9lectriques endommag\u00e9s ou expos\u00e9s.\r\n\r\n<strong>Coup de foudre<\/strong>\r\n\r\nLa foudre endommage rarement les appareils par exposition directe. N\u00e9anmoins, cela peut faire des ravages en d\u00e9clenchant une surtension. Les dommages caus\u00e9s par la foudre r\u00e9sultent g\u00e9n\u00e9ralement d'un impact direct sur les lignes \u00e9lectriques, qui produit une tension \u00e9lev\u00e9e. La foudre qui tombe juste \u00e0 proximit\u00e9 de votre ligne \u00e9lectrique peut entra\u00eener une pointe suppl\u00e9mentaire de tension \u00e9lectrique de plusieurs millions de volts. Les surtensions provoqu\u00e9es par la foudre peuvent d\u00e9truire vos appareils \u00e9lectroniques.\r\n\r\n<strong>Panne de courant ou panne de courant<\/strong>\r\n\r\nLes pannes de courant se produisent g\u00e9n\u00e9ralement en raison d\u2019une panne \u00e0 grande \u00e9chelle du r\u00e9seau \u00e9lectrique, et m\u00eame si le manque d\u2019\u00e9lectricit\u00e9 ne pose g\u00e9n\u00e9ralement aucun probl\u00e8me, le retour \u00e0 la connexion peut souvent le faire. Il est courant de constater une brusque augmentation du courant lorsque le courant est r\u00e9tabli apr\u00e8s une panne. En cons\u00e9quence, cette surtension peut potentiellement endommager tous les appareils branch\u00e9s et les appareils non \u00e9quip\u00e9s de parasurtenseurs.\r\n\r\n<strong>Les parasurtenseurs sont-ils n\u00e9cessaires ?<\/strong>\r\n\r\nSans parasurtenseur, une pointe de tension soudaine et la surtension qui l'accompagne pourraient endommager votre \u00e9quipement.

Surges are also referred to as \u201ctransient voltage\u201d because they\u2019re caused by the sudden presence of an overvoltage traveling through an electrical system.\r\n\r\n<strong>What Causes Power Surge?<\/strong>\r\n\r\nThere are several causes for a power surge. The main reasons are electrical overload, faulty wiring, lightning strikes, and the restoration of power after a power outage or blackout.\r\n\r\n<strong>Electrical Overload<\/strong>\r\n\r\nElectrical overloads can occur when too much power is drawn from a single circuit. This happens most commonly from overusing extension cords and plugging in too many devices into the same circuit.\r\n\r\n<strong>Faulty Wiring<\/strong>\r\n\r\nFaulty wiring is a potential internal cause of power surges, which are more likely to happen with damaged or exposed electrical wires.\r\n\r\n<strong>Lightning Strike<\/strong>\r\n\r\nLightning rarely damages appliances through direct exposure. Still, it can wreak havoc by triggering a power surge. Lightning damage usually results from a direct strike on power lines, which produces a large voltage. Lightning touching down simply near your power line can lead to an extra spike in electrical voltage of millions of volts. Power surges from lightning strikes can destroy your electronics.\r\n\r\n<strong>Power Outage or Blackout<\/strong>\r\n\r\nPower outages typically occur due to large-scale power grid failure, and while the lack of electricity doesn\u2019t usually cause any issues, the return to connection often can. It\u2019s common to experience a sudden jump in current when power is restored following an outage. As a result, this power surge has the potential to damage any plugged-in appliances and devices that do not have surge protectors.\r\n\r\n<strong>Are Surge Protectors Necessary?<\/strong>\r\n\r\nWithout surge protector, a sudden voltage spike and accompanying power surge could damage your equipment. Even if a power surge doesn\u2019t completely ruin your electronics, it can shorten the lifespan of devices, or otherwise harm devices and appliances.\r\n\r\n<strong>How Prevent a Power Surge From Damaging Electronic Devices?<\/strong>\r\n\r\nUsing surge protection devices, especially when combined with a reliable grounding system, will protect electrical devices and appliances from all but the most severe power surges."},"_links":{"self":[{"href":"https:\/\/www.britecelectric.com\/fr\/wp-json\/wp\/v2\/blog\/793","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.britecelectric.com\/fr\/wp-json\/wp\/v2\/blog"}],"about":[{"href":"https:\/\/www.britecelectric.com\/fr\/wp-json\/wp\/v2\/types\/blog"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.britecelectric.com\/fr\/wp-json\/wp\/v2\/media\/794"}],"wp:attachment":[{"href":"https:\/\/www.britecelectric.com\/fr\/wp-json\/wp\/v2\/media?parent=793"}],"wp:term":[{"taxonomy":"blog_category","embeddable":true,"href":"https:\/\/www.britecelectric.com\/fr\/wp-json\/wp\/v2\/blog_category?post=793"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
