A Study on Circuit Topology for the Electrical Power Failure and Open-Phase Fault Detection of Industrial Field

산업현장 정전 및 결상사고 감지회로 토폴로지 연구

This paper proposes an open-phase fault control system using 3-phase neutral voltage. The proposed control system is designed as a new topology which uses the potential difference between neutral point and ground of three phase. The open-phase detection system is also configured to Y-wiring of three capacitance devices of the same capacity to each line of three phase power source R-S-T. This paper also designs a mobile phone application for remote alarm of open-phase fault.
