- Scope
- "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 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 In this international standard@ the term ""HV gas-insulated transmission line"" is abbreviated to ""GIL"". NOTE 2 In this international standard@ the word ""gas"" means gas or gas mixture@ as defined by the manufacturer. NOTE 3 Examples of GIL applications are given: ?C where all or part of the HV gas-insulated transmission line is directly buried; or ?C where the HV gas-insulated transmission line is located@ wholly or partly@ in an area accessible to public; or ?C where the HV gas-insulated transmission line is long and the typical gas compartment length exceeds the common practice of GIS technology."
