Surge arrester
What is a Surge Protector?
A surge protector, also known as a surge arrester or surge suppressor, is an electrical component designed to prevent damage caused by electrical surges.
How does a Surge Protector work?
A surge protector functions by diverting harmful surges away from devices. When a surge occurs, the protector provides a low-resistance path for the surge, effectively channeling the excess current away from connected devices and preventing damage.
Types of Surge Protectors:
- Type 1 Surge Protectors: Installed outside the building, near the electrical entry point, designed to handle surges from direct lightning strikes.
- Type 2 Surge Protectors: Installed at the electrical panel or near sensitive equipment, designed to manage residual surges and voltage variations.
- Type 3 Surge Protectors: Installed directly on sensitive devices like computers and electronics for final surge protection.
How to choose the right Surge Protector?
The choice depends on the building's location, exposure level to surges, and equipment sensitivity.
