Title High-voltage switchgear and controlgear - Part 211: Direct connection between power transformers and gas-insulated metal-enclosed switchgear for rated voltages above 52 kV
Project Number 24478
Abstract/Scope IEC 62271-211:2014 is applicable to single and three phase direct connections between gas-insulated metal-enclosed switchgear (GIS) for rated voltages above 52 kV and transformer arrangements to establish electrical and mechanical interchange ability and to determine the limits of supply of for the transformer connection. This first edition cancels and replaces the first edition of IEC TR 61639:1996 and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) transfer from technical report to international standard; b) the minimum voltage rating was changed from 72,5 kV to above 52 kV; c) update of normative references; d) definition of insulated junction including limit of supply; e) definition of dielectric test of gas-insulated metal-enclosed switchgear for transformer connection in a three phase enclosure; f) addition of interface tolerances at transformer side; g) addition of transformer tolerances in service; h) addition of exceptional loads for bushings and flanges; i) consideration of oil- and gas-insulated transformers; j) inclusion of three-phase enclosed direct connections.

Supersedes  
Superseded by  
Normative reference (6)  

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved


(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat


(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level


(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement


(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn


(6) This list of normative references is purely indicative. The only official list of normative reference is the list of the published standard.
