Publication CODE Title
NBN EN IEC 62271-204:2022 (2022-07) HIGH-VOLTAGE SWITCHGEAR AND CONTROLGEAR - PART 204: RIGID GAS-INSULATED TRANSMISSION LINES FOR RATED VOLTAGE ABOVE 52 kV
 
Price Excl. VAT Total number of pages, tables and drawings
16.00 € 4.
Description
This part of IEC 62271 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. It is intended that this international standard shall be used where the provisions of IEC 62271-203 do not cover the application of GIL (see Note 3). At each end of the HV gas-insulated transmission line, a specific element may be used for the connection between the HV gas-insulated transmission line and other equipment like bushings, power transformers or reactors, cable boxes, metal-enclosed surge arresters, voltage transformers or GIS, covered by their own specification. Unless otherwise specified, the HV gas-insulated transmission line is designed to be used under normal service conditions. Note 1 to entry: In this international standard, the term "HV gas-insulated transmission line" is abbreviated to "GIL". Note 2 to entry: In this international standard, the word "gas" means gas or gas mixture, as defined by the manufacturer. Note 3 to entry: Examples of GIL applications are given: - where all or part of the HV gas-insulated transmission line is directly buried; or - where the HV gas-insulated transmission line is located, wholly or partly, in an area accessible to public; or - where the HV gas-insulated transmission line is long (typically longer than to 500 m) and the typical gas compartment length exceeds the common practice of GIS technology.
