When significantly more voltage comes through wires into devices, it\u2019s known as a power surge.

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\/sv\/wp-json\/wp\/v2\/blog\/793","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.britecelectric.com\/sv\/wp-json\/wp\/v2\/blog"}],"about":[{"href":"https:\/\/www.britecelectric.com\/sv\/wp-json\/wp\/v2\/types\/blog"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.britecelectric.com\/sv\/wp-json\/wp\/v2\/media\/794"}],"wp:attachment":[{"href":"https:\/\/www.britecelectric.com\/sv\/wp-json\/wp\/v2\/media?parent=793"}],"wp:term":[{"taxonomy":"blog_category","embeddable":true,"href":"https:\/\/www.britecelectric.com\/sv\/wp-json\/wp\/v2\/blog_category?post=793"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
