Currently, in all homes and workplaces, we have a large number of electronic devices connected to the power grid, and we need them to function properly, both for daily life and for our work tasks. For this reason, any installation with sensitive devices, of certain value, and that operate continuously should be protected with surge protectors.

Currently, in all homes and workplaces, we have a large number of electronic devices connected to the electrical network, and we need them to function properly, both for daily life and for our work tasks. For this reason, any installation with sensitive devices, of certain value, and that operate continuously should be protected with the necessary surge protectors to ensure the protection and safety of both the equipment and the people.

Although you may know that they are necessary, you might not be entirely clear on what a surge protector is and what it is used for. Below, we help you understand it.

What is a surge protector and how does it work?

A surge protector, also called an electrical protector or voltage suppressor, is a device that connects between the electrical network and the ground. It is designed to protect electrical devices from voltage spikes by managing and controlling the electrical energy of a connected electronic device. A surge protector attempts to regulate the voltage applied to an electrical device by blocking or grounding voltages that exceed a safe threshold. In other words, if a storm causes a surge, this protector can safeguard each and every element of your installation without damage. You have surely heard the expression "better safe than sorry." When it comes to safety and protection against the dangers of a surge, it is essential to choose the best surge protectors.

What types of surge protectors exist?

If you are looking for a surge protector but don't know where to start, first we must understand that surges are increases in voltage in the electrical network that occur when the network voltage exceeds the nominal voltage. There are permanent and transient surges. Therefore, there are different types of surge protectors, and you should choose the one that suits your needs. Below, we show you the main characteristics. Transient surge protector To prevent a transient surge from damaging the devices connected to the installation, a protector is installed that contains varistors that conduct current when the network voltage exceeds its nominal voltage. What equipment can I protect with a transient surge protector? Washing machines, computers, televisions, and other equipment with power electronics. It also provides protection against lightning or when connecting and disconnecting significant loads. Permanent surge protector In the case of a permanent surge, which lasts over time, varistors are not the best option. It is used solely to trip a circuit breaker. This type of configuration is useful because a thermal magnetic circuit breaker allows you to have 3 types of protection with 1 single device: against short circuits, overcurrent, and surges. Permanent and transient surge protector Some manufacturers have devices that integrate the protection of both permanent and transient surges. If you want to know more about them, we recommend consulting a surge protection scheme.
