IEC 62271-213:2021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包括每相的耦合系统（电容、电阻耦合或其他技术），以连接到带电部件（主电路）。 本第一版取消并取代1997年发布的IEC 61243-5第一版和2011年发布的IEC 62271-206第一版。本版本是IEC 61243-5和IEC 62271-206内容的合并。 与IEC 61243-5和IEC 62271-206之前版本相比，本版本包括以下重大技术变更: a)可选输出信号被定义为用于多用途用例； b)仅为电压检测和指示系统(VDIS)定义了一个接口；c)电压限制元件的载流能力的测量被认为是不准确的，在本文件中不考虑。经验表明，耦合元件失效的概率可以忽略不计。

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.
