[China Instrument Network Instrument Industry] In order to ensure that residents use the measurement accuracy of the energy meter, and further regulate the metering supervision and management of the meter, the Gansu Provincial Institute of Metrology completed the 5556 single-phase three-phase commissioned by the Gansu Provincial Academy of Electric Power in June. Electricity meter sampling work.

In order to successfully complete the electric energy metering inspection task, and at the same time faced with the conflicts of electric meters, gas meters, and water meters that were recently submitted by customers, the Gansu Metrology Institute has formulated a detailed sampling inspection plan and made reasonable arrangements for the verification personnel. In the case of a long-distance road travel in Lanzhou New District, professional verification personnel of the Gansu Metrology Institute voluntarily gave up the rest time at noon, making the verification station in working condition throughout the day. After solidarity and unremitting efforts, Gansu Metrology Institute eventually completed the single-phase three-phase electric energy meter sampling inspection commissioned by the Provincial Electric Power Research Institute. The total number of single-phase three-phase electric energy meters was 5556, with a pass rate of 100%.
The random sampling method was taken randomly, and the provincial metrology institute verification personnel were in strict accordance with the national metrological verification regulations to verify the meter identification, basic errors, instrument constants, start-up, creepage, voltage effects, and frequency effects of the energy meter products. One by one detection. All sampling data of the meter detection parameters meet the national allowable error range, so as to ensure the accuracy and fairness of the measurement verification.
