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:
- an optional output signal is defined to be used for multipurpose use cases;
- only one interface is defined for voltage detecting and indicating system (VDIS);
- 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.
