Firstly, the indexes and power values of active meter (including peak (in some areas), peak, level and valley), reactive meter and lighting meter in the current month are calculated from the meter reading records.
If no lighting meter is installed, the lighting electricity consumption of non-residents shall be reduced according to a fixed proportion or quantitative value.
The rest of the electricity is used by large industries.
If it is a high supply and low meter, it should also add variable loss power.
