High-voltage switchgear and controlgear - Part 204: Rigid gas-insulated transmission lines for rated voltage above 52 kV
IEC 62271-204:2022 applies to rigid HV gas?insulated transmission lines (GIL) in which the insulation is obtained, at least partly, by an insulating gas or gas mixture other than air at atmospheric pressure, for alternating current of rated voltages above 52 kV, and for service frequencies up to and including 60 Hz. This second edition cancels and replaces the first edition published in 2011. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:- update to be in line with IEC 62271-1:2017 and alignment of the voltage ratings and the test voltages.- addition of new information for welds on pressurized parts and gas tightness.

High-voltage switchgear and controlgear - Part 204: Rigid gas-insulated transmission lines for rated voltage above 52 kV
IEC 62271-204:2011 applies to rigid HV gas insulated transmission lines (GIL) in which the insulation is obtained, at least partly, by a non-corrosive insulating gas, other than air at atmospheric pressure, for alternating current of rated voltages above 52 kV, and for service frequencies up to and including 60 Hz. This standard cancels and replaces IEC/TS 61640:1998. It is a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - update to be in line with IEC 62271-1:2007 and 62271-203 and alignment of the voltage ratings and the test voltages; - addition of new information for gas tightness and corrosion protection. This publication is to be read in conjunction with IEC 62271-1:2007.
ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.
The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.
The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
With Requirements, quickly access the main part of the normative text!
