Description of BS EN IEC 62271-213:2021 2021This part of IEC 62271 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). The VDIS is applicable on systems with nominal voltage s above 1 kV and service frequencies from 16,7 Hz up to and including 60 Hz. The VDIS is used to detect and indicate the presence or absence of operating voltage . It is not intended to distinguish between voltage not present (i.e. U < 10 % of nominal voltage ) and dead circuit state (i.e. U = 0 V).
The VDIS is fixed on equipment such as switchgear and controlgear according to the IEC 62271 series or transformers according to their own standards. The products designed and manufactured in accordance with this document contribute to the safety of the users, provided they are used by skilled or instructed persons in accordance with safe methods of work and the instructions for use.
