On multi-function Energy Meter Electronic Performance Assessment Methods

Since the twentieth century, the nineties, import 0.2S-level multi-function electronic energy meter measured the leading high-end network gateway, and high-energy meter huge price difference so that the power company meter selection, procurement, face major challenges . how to effectively identify high-quality difference meter, grasp the selection of scale, the power meter to establish a fair selection mechanism to enter the domestic high-end meter Metering dominant position, is the Application of power measurement meter industry sector and an expectation.

Gateway energy measurement has a large capacity, load dynamic range, phase change frequently harsh electromagnetic interference and high reliability characteristics. In view of the special nature of Metering, not all of the 0.2S-level multi-function power meter can be used as Metering in the international arena, Energy Meter called GT & D Table (Generation Transmission & Distribution Application) and the industrial and commercial users multi-function meter billing as C & I form (Commercial & Industrial Application).

Currently, the crossing of international multi-function table lack of uniform standards, national standards that the special requirements of multi-function meter also has limitations, the performance of high-quality multi-function meter difference in how to identify, is currently pressing the power companies need to solve the problem.

Since 2007, the State Grid Corporation of laboratory performance evaluation of energy metering equipment (hereinafter referred to as laboratory) conducted a performance evaluation grid Energy Meter method, the instrument type testing methods and legal metrology procedures, based on the focus argument, the introduction of Energy Meter performance requirements, from multi-dimensional perspective, the introduction of changes in physical conditions and energy meter analysis algorithms and other new technologies, explore the Energy Meter performance evaluation methods, in order to establish a safe, reasonable and fair selection mechanism of the gateway and domestic energy meter high-quality design and development of Gateway Energy Meter Test platform. http://www.jyins.com/
