IEC 60480 GUIDELINES FOR THE CHECKING AND TREATMENT OF SULFUR HEXAFLUORIDE (SF6)
IEC 60480 GUIDELINES FOR THE CHECKING AND TREATMENT OF SULFUR HEXAFLUORIDE (SF6) TAKEN FROM ELECTRICAL EQUIPMENT AND SPECIFICATION FOR ITS RE-USE
INTRODUCTION
Sulfur hexafluoride, SF6, is an essential gas for electrical equipment. Influenced by environmental concerns, the international community, and especially the electrical industry, has made and is still making a substantial contribution towards controlling the environmental impact of the product at all stages of its life, from "the cradle to the grave", as it is defined in ISO 14040.
In line with these efforts and as a complement to them, particular attention has been paid to reclaiming procedures of the SF6 as used in electrical equipment. These procedures allow the re-use of the gas when equipment is maintained, repaired or reaches the end of its service life. This includes acceptable limits for impurity levels, according to experience gained by main users (manufacturers and electrical utilities).
