Water: The Most Powerful Impurity in SF6 Gas-Insulated Switchgear
| Leo LopezSulfur hexafluoride is the gas most commonly used as insulator in power transmission and distribution switchgear. Water, however, can negatively affect the dielectric capabilities of SF 6 gas. To prevent operational and safety issues, it is important to measure and …
Critical Conditions Caused by SF6 Leaks, and How to Avoid Them
| Leo LopezSulfur hexafluoride (SF 6 ) has excellent heat transfer and dielectric characteristics, better than air and other gases, and has been used for decades as insulation and arc quencher in circuit breakers, disconnectors, and switchgear in the power transmission and …
How Changes in Gas Temperature Affect Gas Density Measurements
| Leo LopezCircuit breakers, disconnectors, and switchgear in power transmission and distribution (T&D) operations have been using sulfur hexafluoride (SF 6 ) as insulation for decades. To maintain the excellent thermal conductivity and dielectric strength of SF 6 , …
How Ambient Conditions Can Compromise Density Measurements in T&D SF6-Insulated Equipment
| Leo LopezFor decades, the power transmission and distribution (T&D) industry has been using sulfur hexafluoride (SF 6 ) as the insulator in circuit breakers, disconnectors, and switchgear. The heat transfer and dielectric characteristics of this gas are better than those of …
