Surge protectors are one of the most important devices for protecting electrical equipment from unpredictable power surges. According to market research data, the global demand for surge protectors grew by about 6.2% in 2023 and is expected to continue growing in 2024.
This is mainly due to the growing number of consumers realizing that power surges can cause irreversible damage to expensive electronics. In this article, we will delve into the features of the best surge protectors in 2024 to help you choose the best product to provide comprehensive protection for your devices.
What Is a Surge Protector?
A surge protector is a device used to protect electrical equipment from instantaneous voltage fluctuations, known as surges. It prevents damage to electronic equipment caused by power surges by either directing excessive voltage to the ground or suppressing it within safe limits.
Lightning strikes usually cause surges, fluctuations in the power grid, or surges in current during equipment startup, and surge protectors are effective in minimizing the hazards of these phenomena and prolonging the service life of the equipment.
Types of Surge Protectors
There are different types of surge protectors, each with a specific purpose:
- AC Surge Protectors: Typically used in homes and offices to protect home appliances, computers, and other electronic equipment.
- DC Surge Protectors: These are critical for solar energy systems, industrial setups, and other applications that use direct current (DC).
- Type 1 Surge Protectors: Installed at the source of an electrical system, they protect against direct lightning strikes and large power surges.
- Type 2 Surge Protector: Typically installed at the main service panel to protect electrical systems from residual surges.
- Type 1+2 Combination Surge Protectors: These devices combine the functions of Type 1 and Type 2 to provide comprehensive protection against external and internal surges.
