| Abstract: | The space charge measurement system for coaxial cable is different from the one for flat sample,although the principle of both measurement systems is the same.Based on the analysis of attenuation and disperse,coupling style of impulse electric field and electrode system,the space charge measurement system for coaxial DC polymeric cable,by which the space charge distribution of one de polymeric cable has been measured under the case of 24 h cold after hot,and the result is reliable.The space charge measureme... |
