Due to the decreasing metal line size on complicated integrated circuit, non-destructive analysis strategy was very significant to failure analysis, especially met those special failures which were cold or high temperature failure and light sensitive failure. Two real special cases were presented in this paper to show when and how SDL (Soft Defect Location) technical can be considered to find the...
The concept of potential for natural ventilation (NVP) is defined as the possibility, or probability, to ensure both indoor air quality and thermal comfort by natural ventilation. NVP value can provide the designers significant information to properly design and arrange natural ventilation strategy at the preliminary or conceptual stage of ventilation and building design. In 2005, Lina Yang presented...
Because of its high-capacity, low losses and no electromagnetic interference, the gas-insulated transmission line (GIL), which is a replacement of an overhead line in special environments, has been used for over 40 years, mainly as bus ducts of gas-insulated substations or underground connections in power plants. The insulated and cooling gas in GIL is mainly SF6 or its mixtures, which have high global...
To meet the need of modernization, informationize and safety, the miner lamp management system is designed. It realizes the whole process from miner lamp's hanging up, charging, full-charged and taking away to automated statistics, reporting and checking attendance. So this system is able to offer accurate information to managers in time. On the basis of describing the design background, the paper...
SF6 gas has been widely used currently in electric power systems, such as GIS, GIL and GIT. However, because of the high global warming potential (GWP), SF6 was listed as one of the six restricted gases in "Kyoto Protocol" in 1997. Some fluorocarbon gases with low environmental effect and high dielectric performance are studied as the substitution candidates for SF6. This paper presents...
