Abstract :
Covered conductors have been used, especially in wooded areas on low as well as high voltage overhead distribution lines for preventing brush contact and short circuit faults between conductors. Burndown on covered conductors has become a significant problem. The burndown mechanism is complicated since it is determined by combinations of the various types of insulators, ties, and conductors. In order to investigate the burndown mechanism, a finite element analysis is carried out to identify the electric field around the insulator. A newly developed electric field digital simulation system is reported in which a finite element analysis method considering isoparametric triangular and line elements is developed. A new color display method for electric potential and electric field distributions with lines of electric force is also described as a means of observing the results
