高压开关设备和控制设备-第213部分：电压检测和指示系统

[中文适用范围]： IEC 62271的本部分适用于安装在室内和室外高压设备上的电压检测和指示系统（VDIS）。本文档定义的 VDIS 包括每相一个耦合系统（电容、电阻耦合或其他技术） [外文原描述]： IEC 62271-213:2021 is applicable to the voltage detecting and indicating system (VDIS) to be installed on indoor and outdoor high-voltage equipment. The VDIS as defined by this document includes a coupling system per phase (capacitive, resistive coupling or other technology) to connect to live parts (main circuit). This first edition cancels and replaces the first edition of IEC 61243-5 published in1997 and the first edition of IEC 62271-206 published in 2011. This edition constitutes a merging of the content of IEC 61243-5 and IEC 62271-206. This edition includes the following significant technical changes with respect to the previous editions of IEC 61243-5 and IEC 62271-206: a) an optional output signal is defined to be used for multipurpose use cases; b) only one interface is defined for voltage detecting and indicating system (VDIS); c) the measurement of the current carrying capacity of the voltage limiting element is considered as inaccurate and is not considered in this document. The experience shows that a probability of the failure of the coupling element is negligible.
