Abstract

The present study presented the implementation of a remote control/supervision system for guard lamps used in public illumination with little endeavor by far for safe management, which makes possible to supervise the state and to control the functions remotely including electric safety elements. Especially, the developed system adopts the measurement algorithm for detecting resistive leakage current(Igr) flowing based on the phase difference checkable for sensing at a monitor, being allowable for monitoring at MMI and transmitter for data transmittance. To verify reliability about the algorithm to accurately detect Igr leakage current, the laboratory-based functional test was performed.

본 논문에서는 일반용 전기설비 중에서 전기안전관리의 사각지대로 분류되는 보안등 전기설비를 대상으로 전기안전요소들을 계측하고 원격 모니터링 할 수 있는 보안등 원격점검시스템을 개발하였다. 단말기에서 센싱하는 누설전류는 위상차 측정법을 이용한 저항성분 누설전류(Igr) 측정 알고리즘을 이용하였으며, 계측데이터 전송을 위한 중계기와 MMI에서 모니터링 할 수 있는 시스템을 제작하였으며, Igr 누설전류 검출 알고리즘의 타당성을 확인하기 위해 실험실 기반의 성능시험으로 누설전류의 안정도를 확인하였다.
