ITPEC FE Morning April 2020 Question 57
ITPEC FE Morning April 2020 — Question 57 of 80
An SPD (Surge Protection Device) absorbs voltage spikes caused by lightning strikes, preventing damage from reaching equipment through communication cables.
Why not others:
- (b) Digitalizing control circuits — modernizes power facility management, does not block voltage surges
- (c) Private power generator — protects against power outages, not over-voltage spikes
- (d) Splitting communication wire into two paths — provides redundancy against line failure, not surge protection
Key rule: Lightning = over-voltage → SPD; power outage → generator/UPS.
