ITPEC FE Morning October 2022 Question 73
ITPEC FE Morning October 2022 — Question 73 of 80
A smart meter is a digital electricity meter with communication and device-management functions. It collects, transmits, and displays energy data — but it does not store or supply electricity.
(a) is the correct answer (NOT appropriate): Acting as an auxiliary power source during a power failure is the role of a UPS (Uninterruptible Power Supply), not a smart meter. Smart meters have no battery backup capability for powering other devices.
Why not others:
- (b) Automatic meter reading is a core smart meter feature — it eliminates manual readings.
- (c) Visualizing power consumption raises user awareness and encourages energy-saving behavior.
- (d) Demand response allows the grid operator to signal smart meters to reduce/shift load during peak hours — a key smart grid function.
Key rule: Smart meters measure and communicate energy data; they do not generate or store electricity.
