Surge protection

Surge protection devices are crucial components in safeguarding electrical and electronic equipment from transient overvoltages. These sudden, short-duration increases in voltage can arise from various sources, including lightning strikes, utility switching operations, or even the operation of large electrical motors. By diverting excess voltage away from sensitive equipment and safely channeling it to the ground, surge protectors prevent damage, data loss, and costly downtime. They are widely employed in residential, commercial, and industrial settings to ensure the reliability and longevity of everything from household appliances and computers to complex industrial control systems.

Within the realm of surge protection, several distinct types cater to different protection needs. Lightning current arresters are designed to handle extremely high energy surges, primarily those caused by direct or nearby lightning strikes. They are typically installed at the service entrance of a building. Surge arresters (often referred to as SPD Type 2) offer protection against indirect lightning effects and switching overvoltages, commonly installed within distribution boards. Combination arresters integrate the functionalities of both lightning current and surge arresters, providing comprehensive protection against a wider range of overvoltage events in a single device.
