Calculation of the 3—D Electric Field in SF_6 Zinc—Oxide Lightning Arrester |
| |
| Abstract: | This Paper has discussed the calculation of the 3-D electric field in SF_6 zinc-oxide lightning arrester. To calculate the voltage distributions in a metal arrester, a computer program based on surface charge method has been developed. In order to improve the calculating accuracy of the singular inte-gral, a combinated method of the numerical and analytical methods has been introduced. In this method, each curved surface on which the charge is distributed and divided into many curved surface elements instead of planar elements. This computation procedure is simplified by using numerical integration based on local coordinate. This paper also presents the method of treating a“floating potential”problem. |
