摘要：

Two test methods have been developed to simulate the conditions causing flashover of DC wall bushings at working voltage. One is based on the clean fog pollution test. The other is a rain test, with part of the bushing unwetted. The effect of varying test parameters has been measured and five variants of the rain test have been adopted for measuring the performance of a wall bushing. Its performance compared unfavorably with that of an empty porcelain shell. Various numbers of booster sheds, (removable silicone - rubber cones fitted round the bushing) have been found to improve its performance substantially. © 1990 IEEE
