Leads to interesting questions such as how the (time-based) metering is affected in this situation.
- Piskvorrr 9y agoSure it is time-based? What I've seen is that the meter sits right on the power line, and can measure the energy consumption quite directly. As for peak/off-peak, this is usually signalled by the provider, using AC as a carrier wave, e.g. https://en.wikipedia.org/wiki/Zellweger_off-peak https://en.wikipedia.org/wiki/Zellweger_off-peak
- TickleSteve 9y agoyes, the meter sits on the power line. Thi sis referring to the clock-source for the metering functionality. In some meters, this is derived from the mains frequency (usually as a fallback tho).
