What is the primary role of a surge protector in grounding systems?

The primary role of a surge protector in grounding systems is to divert surges to ground. Surge protectors are designed to prevent voltage spikes, which can arise from lightning strikes, utility switching, or other transient voltage events, from damaging electrical devices and systems. When a surge occurs, the protector detects the excessive voltage and provides a path for it to flow safely into the ground, thus preventing it from entering sensitive electronics or circuitry.

This function is critical in maintaining the integrity of electrical systems, as it helps to ensure that equipment remains operational and unharmed by potentially destructive voltage increases. By safely redirecting these surges, surge protectors play a vital role in protecting both equipment and personnel from electrical hazards.
