Abstract

MOF insulating cover used in 22.9 kV substation hasn't shown good performance in terms of electrical safety because of its defect by short clearance MOF cover and each input and output wire junction part. The MOF cover is easily moved by outside environment as wind or rain weather because of different size MOF cover and insulating busing, also can be leaded to breakdown by tracking. Therefore, we propose MOF cover which effectively prevents from electrical accidents in this paper. To decrease the electric field concentrated on specific part, we roundly design the shape of MOF cover and clearance between cover and live part was adjusted to be longer than before. The proposed MOF cover is evaluated by using the electric field solution program.
