A Study on the Bypassing Device for Short-fault Current produced in Low Voltage Distributed Line

저압배전계통에서 발생한 단락전류의 Bypassing 장치에 관한 연구

In this paper, we designed basic concept and structure of bypassing device which promoted the activity of low voltage line-fuse, when it perceived the too small short-fault current to activate line-fuse which located at the between secondary of pole transformer and home immediately. And we study displacement of bypass contact and electromagnetic force caused by the short-fault current by the basic experiment to understand the basic characteristic of bypassing movements.
