IEC 62271-213:2021适用于:；电压检测和指示系统（VDIS）；安装在室内外高压设备上。 这个VDIS；如本文件所定义，包括连接到带电部件的每相耦合系统（电容、电阻耦合或其他技术）；（主电路；）。 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。本版本合并了IEC 61243-5和IEC 62271-206的内容。 本版本包括与IEC 61243先前版本相关的以下重大技术变更- 5和IEC 62271-206: a） 一个可选的输出信号被定义为用于多用途用例； b） 只有一个；界面定义为:；电压检测；和指示系统；(VDIS);； c） 测量变压器的载流能力；限压元件；被视为不准确，本文件不予以考虑。经验表明，系统失效的概率；耦合元件；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.
