High-voltage switchgear and controlgear - Part 213: Voltage detecting and indicating system EN IEC 62271-213:2021

Publication date:   Nov 17, 2021

Scope

IEC 62271-213:2021 is applicable to the <em>voltage detecting and indicating system (VDIS)</em> to be installed on indoor and outdoor high-voltage equipment.

The <em>VDIS</em> as defined by this document includes a coupling system per phase (capacitive, resistive coupling or other technology) to connect to live parts <em>(main circuit</em>).

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 <em>interface</em> is defined for <em>voltage detecting</em> and <em>indicating system</em> (<em>VDIS</em>);

c) the measurement of the current carrying capacity of the <em>voltage limiting element</em> is considered as inaccurate and is not considered in this document. The experience shows that a probability of the failure of the <em>coupling element</em> is negligible.
