Computation of a kind of electric field distribution of 10kV composite insulator coated by ice

In this paper, based on a kind of 10kV composite insulator computation model and by means of finite element method, the electric field distribution magnitude of composite insulator coated by different icicle length has been calculated, respectively under icing and de-icing condition. And it could be found that nether in icing or ice-melting condition, the max magnitude of electric fields around composite insulator coated by ice have little changed. Moreover, the electric field strength around the icicle increases along with the increasing of the length of icicle. Compared to the results under freezing state, at the ice-melting state, the electric field distortion nearby the icicle tip will be even more serious. In the end, several useful measures about how to improve the electric performance of composite insulators coated by ice have been summed up.
