In order to strengthen the measurement and supervision of the trade settlement energy meter, the accuracy and reliability of the energy meter will be guaranteed, and the legitimate rights and interests of the country, the collective, and the general public will be guaranteed. In April 2011, the Anhui Provincial Bureau of Quality Supervision organized a provincial-level measurement and random inspection of the province's trade settlement single smart energy meter. Quzhou's pass rate is 100%.
Pursuant to the relevant requirements of the Provincial Bureau of Quality Supervision, the Bureau of Quzhou Bureau of Quality Supervision conducted a random inspection of 100 smart energy meters in Zhangzhou on April 12th. Among them, 40 have been randomly selected for use in residential communities such as Shanshui Renjia, Hongsanhuan Homestead, Zhujinjia Garden, Lantian West District, and Huifeng Park. The focus is on users with higher power consumption after replacing the smart energy meter. The consent of the residents was obtained at the time of collection and the replacement of the electric energy meter was promptly installed. For the first installation to be installed, a random sample of 60 power supply companies will be selected. After random inspections, the Bureau of Science and Technology of Anhui Province sent the verification according to the “Electrical Energy Meter Verification Regulations†(JJG569-1999). The verification items include power frequency withstand voltage test, visual inspection and power inspection, start test, and creep test. Check the number of indicators, determine the basic error of energy measurement, determine the estimated value of the standard deviation of energy measurement, determine the daily timing error, and the time switching error and other 9 items. 100 single smart energy meters checked in our city were verified by the Anhui Institute of Scientific and Scientific Research, and all measurement performances were in line with the requirements.
A total of 1,531 single-phase smart energy meters of class 2.0 had been spot-checked in the province, and 1,523 were qualified, with a pass rate of 99.48%. From the analysis of the results of the spot checks, smart meter performance is generally good, and the qualified rate is high. The verification regulations stipulate that the allowable error of the individual smart energy meter energy measurement of class 2.0 is ±2.0%. The majority of the basic error of the energy measurement in the province's qualified electric energy meter is within ±0.4%, which is far less than the standard requirement. Allowable error.
