GB/T 17215.6的本部分规定了对象标识系统(OBIS)的总体结构并将测量设备中的所有常用数据项映射到其标识代码。
OBIS为测量设备中的所有数据都提供唯一的标识符,不仅包括测量值,而且还包括仪表设备的配置或获取测量设备运行状态的抽象数据。本部分定义的ID代码用作标识于:
——接口类的各种实例或对象的逻辑名,其定义参见GB/T 17215.662;
——通过通信线传输的数据;
——测量设备显示的数据(参见附录A中A.2)。
本部分适用于各种类型的测量设备,例如:全集成化电表、模块化仪表、费率附件、数据集中器等。
为了覆盖其他非电能的测量设备,组合式测量设备测量多种能量类型或者具有多个物理测量通道,为此引入媒质和通道的概念。
注:在EN 13757-1:2014中为测量设备定义了一些非电的数据标识符:热分配表、热能表、气表、冷水表和热水表。

This part of GB/T 17215.3 specifies the terms and definitions, classifications, technical requirements, accuracy classes and test methods of static meters connected via electronic transformer (hereinafter referred to as “meters”).
This document is only applicable to newly manufactured meters which have small (signal) analog input and are installed in the networks with a reference frequency of 50Hz or 60Hz to measure the a.c.electric energy and applies to their type tests only.
This document is applicable to the meters consisting of elements such as measuring unit and display enclosed together in a meter case.
This document may be used as reference for meters that have a small (signal) analog input only in the current circuit.
This document is not applicable to meters with digital inputs.
NOTE The transformers intended to connected to the meter refer to GB/T 20840.7-2007, GB/T 200840.8-2007 and DL/T 1155-2012.
