ITPEC FE Morning October 2018 — Question 58 of 80
Surge Protection — An SPD (Surge Protection Device) absorbs or diverts over-voltage spikes caused by lightning strikes, protecting connected equipment.
The correct answer is a): connecting the communication cable and computer through an SPD. This device is specifically designed to clamp voltage surges before they reach sensitive hardware.
Why not the others:
- b) Digitalizing control circuits of power facilities relates to modernizing power plant operations, not protecting end-user equipment from lightning surges.
- c) A private power generator provides backup power during outages but does not protect against voltage spikes traveling through communication cables.
- d) Splitting communication wires into two paths adds redundancy for availability but does nothing to prevent over-voltage damage from a lightning strike.
Key rule: Lightning protection = SPD. Generators handle power loss; redundant paths handle link failure. Only an SPD handles voltage surges.
