도시철도용 몰드변압기의 부분방전 계측을 위한 시스템 구현

초록

Recently in Korea, optimal maintenance related systems that prevent accidents by determining urban railway electric power facility replacement intervals have been adopted. Various condition monitoring technologies such as partial discharge measurement, current measurement, image analysis, supersonic wave analysis have been developed. Also, the evolution of Information technology has made possible Internet protocol based condition monitoring. In this paper, a method to monitor condition of mold transformers of urban railway electric power facilities online using a fault detection device that checks malfunctions of insulation is introduced.
