154㎸ 활선 애자련의 불량애자를 검출하는 활선애자 점검기 개발

To prevent an insulator failure, a new inspection system is presented for 154㎸ insulator strings. The inspection system detects fault insulators by measuring resistance and voltage of each insulators in the 154㎸ insulator string. The inspection instrument obtains autonomously insulation resistance and assigned voltage along the insulator string. The insulator inspection instrument is manipulated by two operators. In addition, a set of mechanism is applied to prevent the system from being reset under live-line condition. We confirmed its effectiveness through experiments.
