Corona discharge affected by an electrified floating-metal in unipolar ion flow field is of interest in understanding the flashover phenomena of non-uniform field gap with a floating metal which appears often in dc electric power system. In the present work, flashover voltage characteristics and corona mode in a positive needle-to-plane gap of 30 to 180 mm with a floating metal are investigated experimentally. The metal is sphere in shape for the simplicity of analysis and its radius was changed from 2 to 15 mm to find the size effect.
The results show that the sequence of corona discharge mode with the applied voltage is unchanged from that in the absence of floating metal, but corona activity and onset voltage of each corona mode are influenced strongly by the existence of floating metal, especially the metal location. The flashover characteristics are discussed on the bases of measured characteristics of corona mode.
