DDDZY-102-Z fee-controlled smart meter will have a record of electricity theft.

The total electricity consumption is not consistent with the amount of electricity shown on the meter, and it is easy for the power supply office to find out who is stealing electricity.

Users with IC cards to the power supply department to pay for the purchase of electricity, the power supply department with the power sales management machine to write the purchase of electricity into the IC card, the user with the IC card in the induction area brush non-contact IC card (referred to as the brush card, the same below), you can close the gate power supply, power supply will be taken away after the card. When the remaining power in the meter is equal to the alarm power, the alarm (or buzzer alarm) will be pulled to cut off the power, at this time, the user can return to normal by brushing the card in the induction area, at this time, the user can restore the power supply by brushing the card in the induction area; when the remaining power is zero, the alarm will be automatically pulled to cut off the power, and the user has to hold the card to pay the fee for the purchase of power again, and only then can he/she can restore the power supply. This effectively solves the problem of difficult door-to-door meter reading and collection of electricity charges. At the same time, the user's power purchase information is managed by microcomputer, which is convenient for inquiry, statistics, charging and printing bills. It has the advantages of double display, accurate measurement, stable precision, safety and confidentiality, reliable performance, complete functions, low power consumption, simple and convenient operation and so on. There are also low-cost single-display power meters.
