ITPEC FE Subject A April 2025 Question 56
ITPEC FE Subject A April 2025 — Question 56 of 60
A smart meter measures electricity consumption, transmits data automatically, and can control connected devices via demand response. It is not an energy storage or generation device.
- •(b) Automatic meter reading — core smart meter function
- •(c) Visualizing consumption to promote energy saving — core smart meter function
- •(d) Demand response to reduce peak load — core smart meter function (device management)
Why not (a): Acting as an auxiliary power source during a power failure requires a battery or generator (e.g., UPS). A smart meter has no energy storage capability — it only measures and communicates.
Key rule: Smart meter = measure + communicate + control devices. It does not store or supply electricity.
