Introduction

Power and T&D Industry is developing rapidly with more and more high-voltage and ultra-high-voltage switchgear used, and the demand of GIS is soaring with it. SF6 is widely used in GIS as a good insulation and interruption gas. The compartment tightness of GIS is very critical to its lifetime and the maintenance cost, and the leakage of SF6 will impact the safety and health of staffs and the global warming, too.
