Why does the power company change the meter for the people every few years?
The electric energy meter is one of the household electric equipments that is subject to compulsory measurement by the state and is specially tested by the state-authorized verification department. The product can only be used after the product is qualified. The service life of the electric meter is determined by the verification department as long as the service life of the meter expires. It is necessary to replace all new meters. The lifespan of meters for household use is 6 - 8 years.
The service life of low-voltage three-phase meter is 5 years. The service life of high-voltage three-phase meter is 3-4 years. The electricity meter used in our home is improved again and again. Now all the electronic smart meters are used. The smart meter has many functions and can be intelligent. Deductions, accurate measurement, power memory, remote feedback, excess or balance alarms, etc., the power company must change the meter every few years because:
First, the country has clear requirements on the number of years of operation of the electric energy meter, and it will be forced to replace the number of years of operation.
Second, with the development of science and technology and the improvement of people’s living standards, old-fashioned meters cannot meet the needs of the new era and are gradually being replaced by smart meters. All replacements are normal. Third, smart meters are exposed to the sun and long-term operation. The degree of insulation and pressure resistance of the smart meters will decrease with the safety factor of the environment, and corrosion corrosion will gradually decrease. In order to allow users to use them safely, they must be promptly replaced.
