In addition, the wavelet transform is applied to suppress noises within field-measured signals. The presence of free moving metallic particles and partial discharge (PD) deteriorates the insulation strength of GIS and GIL. So, it is necessary to detect partial discharge in GIS at an early stage before the system failure and extensive damage to the equipment. From the field-measurement signals and corresponding wavelet analysis, it is proved that the noisy can be eliminated as well as the signals identification can be increased. Furthermore, PD signals could be detected in GIS and GIL. Ray-Lee Lin Jiann-Fuh Chen 林瑞禮 陳建富 2006 學位論文 ; thesis 86 zh-TW |
