Zusammenfassung:Disclosed is an abnormal voltage pre-detection system and a method utilizing DCU, which detect unbalanced current in advance and reinforce the same preemptively by utilizing current information for each phase. The abnormal voltage pre-detection system includes: multiple data concentration units (DCUs) which measure the current for each phase; and a management server which calculates the unbalanced current flowing in the N phase among the currents for each phase and provides alarm information to a facility operator when the unbalanced current exceeds a certain value. 각상별 전류 정보를 활용하여 불평형 전류를 사전에 검출하고 선제적으로 보강할 수 있는 DCU(data concentrating unit) 활용 이상 전압 사전 검출 시스템이 개시된다. 상기 이상 전압 사전 검출 시스템은, 각 상별 전류를 측정하는 다수의 DCU(Data Concentration Unit), 및 상기 각 상별 전류중 N상 흐르는 불평형 전류를 계산하고, 일정값이상 발생시 설비 운영자에게 알람 정보를 제공하는 관리 서버를 포함하는 것을 특징으로 한다.
