Electric surge protectors are essential devices for any electrical installation, as their main function is to protect against short circuits and overloads, preventing damage to electrical equipment and installations, as well as possible fires. The more technical term for a surge protector is: Surge Protection Device (SPD).<\/p>\n
A surge protector or SPD can be installed in incoming service networks, such as electrical power, telephone, and cable TV, to name a few. It consists of one or more poles, which are switches responsible for regulating the flow of electrical current.<\/p>\n
Among the main features of a surge protector are:<\/p>\n
- \n
- Rated capacity:<\/b> indicates the maximum voltage that the surge protector can withstand.<\/li>\n
- Rated voltage:<\/b> indicates the working voltage of the surge protector.<\/li>\n
- Trip curve:<\/b> determines the time it takes for the surge protector to interrupt the current in the event of an overload or short circuit.<\/li>\n<\/ul>\n
What is an electrical surge protector used for?<\/b><\/span><\/h2>\n
It is important to note that the terms \u201cvoltage surge protector\u201d and \u201celectric surge protector\u201d refer to the same device, and their function is clear: to ensure the safety and proper functioning of connected equipment and devices in the event of voltage instability that may occur somewhere.<\/p>\n
Unlike surge suppressors, which divert excess energy to ground, voltage cut-offs act more directly by automatically cutting off power when they detect a significant voltage spike in the electrical network.<\/p>\n
Fluctuations in the power supply can have various causes, from electrical storms to maneuvers in the electrical network, to the switching on or off of large loads. Whatever the reason, power surge protectors are essential for protecting our electronic equipment and devices at all times.<\/p>\n
Types of power surge protectors<\/b><\/span><\/h2>\n
There are different types of surge protectors depending on their application and surge current diversion capacity:<\/p>\n
By application:<\/b><\/p>\n
- \n
- Surge protectors or DPS for power grid installations and equipment with a rated voltage of up to 1000 V.<\/li>\n
- Surge protectors or DPS for computer installations and equipment with a voltage of up to 60 V. Also known as surge arresters.<\/li>\n<\/ul>\n
By surge current diversion capacity:<\/b><\/p>\n
- \n
- Lightning surge arresters: <\/b>installed at points of intersection between areas protected against direct or nearby lightning strikes.<\/li>\n
- Surge arresters: <\/b>installed at points of intersection to protect against distant lightning strikes and surges caused by switching processes and electrostatic discharges.<\/li>\n<\/ul>\n
Applications of electrical surge arresters<\/b><\/span><\/h2>\n
An electrical surge protector plays a fundamental role in protecting the proper functioning of computer equipment containing important data from various business processes. For this reason, there are applications in various environments:<\/p>\n
- Surge arresters: <\/b>installed at points of intersection to protect against distant lightning strikes and surges caused by switching processes and electrostatic discharges.<\/li>\n<\/ul>\n
- Lightning surge arresters: <\/b>installed at points of intersection between areas protected against direct or nearby lightning strikes.<\/li>\n
- Rated voltage:<\/b> indicates the working voltage of the surge protector.<\/li>\n
