차량탑재용 온라인 피뢰기 진단장치의 설계 및 제작

In this paper, we described an on-line analyzer of arresters for use in trains by measurement of leakage current. The analyzer is composed of a detection module and a server which is installed in a railway yard. The detection module consists of an air-gap and a resistor to measure the leakage current flowing an arrester. The magnitude of leakage current is transmitted to the server through a zigbee module when the train arrives a railway yard. The server displays train number, magnitude of leakage current and condition for arresters.
