IEC 61869-1:20 23适用于新制造的仪表变压器，用于标称电压高于1 kV AC或1.5 kV DC的应用，具有用于测量、保护和控制目的的模拟或数字次级信号，额定频率为15 Hz至400 Hz，或用于DC应用。 IEC 61869-201涵盖了低压系统（标称电压≤1 kV AC或≤1.5 kV DC）中应用的仪表变压器的一般要求。 IEC 61869的这一部分是产品系列标准，仅涵盖一般要求。对于每种类型的互感器，产品标准由本文件和相关的具体产品标准组成。 IEC 61869的这一部分包含模拟和数字辅助信号的误差限制要求。互感器数字接口的其他特性在IEC 61869-9中作为IEC 61850水平标准系列的应用进行了标准化，涵盖了电力设施自动化的通信网络和系统。 IEC 61869的这一部分考虑了带宽要求。谐波精度要求和抗混叠滤波器要求见5.7。 IEC 61869-1:20 23取消并取代了2007年发布的第一版和IEC 61869 6:2016。本版构成技术修订版。 与上一版相比，此版本包括以下重大技术变更: a)与IEC 61869-6:20 16合并； b)新范围:标称电压>1 kV AC或1.5 kV DC的高压应用设备； c)将某些特殊试验新分类为型式试验或常规试验； d)附加型式试验、附加特殊试验和新的试车试验条款； e)新的附件E、F、G和I。

IEC 61869-1:2023 is applicable to newly manufactured instrument transformers intended for applications where the nominal voltage is higher than 1 kV AC or 1,5 kV DC, with an analogue or a digital secondary signal for measuring, protection and control purposes, with rated frequencies from 15 Hz to 400 Hz, or for DC applications.
The general requirements for instrument transformers for applications in LV systems (nominal voltage ≤ 1 kV AC or ≤ 1,5 kV DC) are covered by IEC 61869-201.
This part of IEC 61869 is a product family standard and covers general requirements only. For each type of instrument transformer, the product standard is composed of this document and the relevant specific product standard.
This part of IEC 61869 contains the requirements for the limits of the errors both for analogue and digital secondary signal. The other characteristics of a digital interface for instrument transformer are standardised in IEC 61869-9 as an application of the IEC 61850 horizontal standard series, covering communication networks and systems for power utility automation.
This part of IEC 61869 considers bandwidth requirements. The accuracy requirements on harmonics and requirements for the anti-aliasing filter are specified in 5.7.
IEC 61869-1:2023 cancels and replaces the first edition published in 2007 and IEC 61869 6:2016. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) merger with IEC 61869-6:2016;
b) new scope: equipment for HV applications with a nominal voltage > 1 kV AC or 1,5 kV DC;
c) new classification of some special tests as type tests or routine test;
d) additional type tests, additional special tests and new clause for commissioning tests;
e) new annexes E, F, G and I.
