How Internet Cable Surge Protectors Work

The Technology Behind Surge Protectors

Mechanisms for diverting excess voltage

An internet cable surge protector safeguards your equipment by redirecting excess voltage away from sensitive components. When a current surge occurs, the protector channels the overvoltage to the ground, ensuring your cables and devices remain unharmed. This process happens almost instantaneously, preventing damage before it can occur.

Surge arresters are designed to discharge at lower voltage levels than what would harm your equipment, offering reliable protection against overvoltages.

Different mechanisms work together to achieve this protection:

  • Gas Discharge Tubes (GDT): These activate when voltage exceeds a certain threshold, safely guiding the excess current to the ground.

  • Transient Voltage Suppression Diodes (TVS): These respond rapidly to voltage spikes, conducting the surge current away from your equipment.

  • Negative Temperature Coefficient (NTC): These components increase resistance as temperature rises, limiting the flow of current during a surge.
