DANSK DS/EN IEC 62271-213 PDF

IEC 62271-213:2021 is applicable to the ;lt;em;gt;voltage detecting and indicating system (VDIS);lt;/em;gt; to be installed on indoor and outdoor high-voltage equipment. The ;lt;em;gt;VDIS;lt;/em;gt; as defined by this document includes a coupling system per phase (capacitive, resistive coupling or other technology) to connect to live parts ;lt;em;gt;(main circuit;lt;/em;gt;). 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 ;lt;em;gt;interface;lt;/em;gt; is defined for ;lt;em;gt;voltage detecting;lt;/em;gt; and ;lt;em;gt;indicating system;lt;/em;gt; (;lt;em;gt;VDIS;lt;/em;gt;); c) the measurement of the current carrying capacity of the ;lt;em;gt;voltage limiting element;lt;/em;gt; is considered as inaccurate and is not considered in this document. The experience shows that a probability of the failure of the ;lt;em;gt;coupling element;lt;/em;gt; is negligible.
