2023-02-14 00:00

As an energy metering product, an electric energy meter is also an electronic product that needs to meet a series of standards; Mainly by EN50470, IEC62052-11 2020, IEC62053-21 2020, GB/T 17215.211-2021, GB/T 17215.321-2021, etc., these standards specify index requirements for the power performance of Watt hour meters. Electrostatic discharge immunity test, radio frequency electromagnetic field immunity test, fast transient burst, conducted disturbance immunity test induced by radio frequency field, surge immunity test, attenuated oscillation wave immunity test, radio interference suppression, measurement accuracy error, etc. In the research and development process, it is necessary to use professional equipment to test these functional performance indicators to ensure that the designed products meet the requirements of the standard.

As a R&D and manufacturing enterprise of energy meter, Yongtailong attaches great importance to the investment of laboratory testing equipment and follows the standard requirements to update and iterate the testing equipment. In the laboratory hardware facilities, software management passed the CNAS certification. This signifies that Yongtailong has established a quality management system laboratory in line with international standards, and the hardware facilities, management level and testing technology capability have reached the requirements of national and even international standard quality management system, and the testing report has international mutual recognition, authority and credibility. With the progress of the times, the market requirements for energy meters are getting higher and higher, and more and more functional requirements, thus increasing the difficulty of research and development of energy meter products. Multi-functional meters, smart meters, prepaid meters, Internet of things meters, etc. have become the mainstream market demand products. The CNAS laboratory certification of China electricity meter manufacturers is also from a long-term perspective to lay the foundation for the rapid development of energy meters.

China National Accreditation Service for Conformity Assessment (CNAS) is also a full member of International Accreditation Forum (IAF), International Laboratory Accreditation Cooperation (ILAC), Asia Pacific Laboratory Accreditation Cooperation (APLAC) and Pacific Accreditation Cooperation (PAC). Laboratories accredited by CNAS in China will also be accredited by the above-mentioned international organizations and have an important position in the international accreditation activities.

Through the requirements and positioning higher than the industry standard of electric energy meter, we will continuously improve our professional level and technical ability, enhance our competitiveness, and provide support to the production, technology, research and other work of Yongtailong, and move forward to become a leading enterprise in the field of global electric power measurement and measurement and control with the strategy of product leadership. To provide value to customers, we focus on energy measurement and testing solutions, and become a new type of power product solution provider under the background of "double carbon".
