PD Properties and Gas Decomposition Analysis of Gas Insulation Media

The need to develop new gas became mandatory requirement to protect environment condition which was decided in Kyoto Protocol. For this reason various industries are recommended to decrease their consumption of SF6 gas. At the same time, many researchers all over the world are trying all their best to search the best solution to minimize or to avoid the greenhouse gas emission. The utilizing of environmental friendly gas insulating media such as vacuum and CF3I to the electric power apparatus give high impact to improve climate change due to the low GWP emission of greenhouse gases. It is realized that the rapid progress on technology development is essential and important for the better life with the conservation of environment. This research work dealt with the PD properties and diagnostic technique on vacuum performance in practical VI, and decomposition by-products analysis of CF3I gas.
