전기화재 통계분석을 통한 효율적인 전기설비 원격감시 방안 도출

Despite the technical advance and efforts to decrease electrical fires, the ratio of electrical fire has been maintained at around 20% for the last ten years. To realize a safe electrical system, regular inspection of the electrical system has been conducted; however, regular inspection is ineffective in monitoring the electrical system's abrupt failure. As a result, many electrical facilities have left unmonitored without proper treatment. Regarding these factors, national regulations to real-time monitor electrical facilities in remote were established in 2020, and the adoption of remote inspection started to increase for early fault detection as well as reduced electrical fires. In this paper, the priority of electrical facilities monitoring was derived through national fire statistics for their effective operation. The statics indicates that the reduction in loss and casualties from the fire will be the greatest if remote monitoring systems are introduced in industrial and medical facilities. In addition, preemptive arc fault detection and on-site preventive maintenance of faulty equipment before monsoon season and cold winter will significantly decrease electrical fires. According to the statics-based analysis, we estimate the effect of remote monitoring on reducing electrical fire depending on the measuring factors and period. If real-time monitoring systems for leakage and over-current are installed in electricity facilities, they will reduce electrical fires caused by arc, over-current, and leakage. We expect a 20 - 25% of electrical fire (~1900 cases/year) reduction if remote monitoring systems are implemented on all consumer sites.
