One is the high sensitivity of smart meters, which will cause the illusion of "running fast" in vision.

    Secondly, it's not that smart meters go fast, but that smart meters can detect the weak current that old meters can't detect, and the sensitivity of old mechanical meters decreases with the increase of service life.

    When replacing the energy meter, when the filing time of the work order conflicts with the reading time of the current month, the remaining electricity of the old meter will be put into the reading electricity of the next month for calculation after the replacement of some customers' meters. Therefore, the corresponding electricity consumption period of the first month of the new meter actually exceeds one month. On the face of it, the first month of the new meter costs more than the last month of the old meter.
