Zusammenfassung:The present invention relates to a system for detecting partial discharge and defect locations based on microelectromechanical systems (MEMS) acceleration sensors and a detection method for the same. Multiple partial discharge and defect location detection devices embedded with MEMS acceleration sensors for detecting abnormal signals of partial discharge and defects when a partial discharge or a defect due to the partial discharge occurs in a vibration detection target facility such as a gas insulated switchgear (GIS), a gas insulated bushing (GIB) unit, a transformer, a distribution board, cables, or a rotor (motor, power generator) are simply attached to the outer surface of the vibration detection target facility such as GIS pipes to let the MEMS acceleration sensors determine the magnitude and occurrence sequence of the vibration occurring on the facility and detect the accurate locations of partial discharge and defects, thereby preventing secondary accidents in the electrical facilities due to the partial discharge and defects. 본 발명은 MEMS 가속도센서 기반 부분방전/결함 위치 검출 방법 및 검출시스템에 관한 것으로, 전기시설물인 GIS(Gas Insulated Switch gear), GIB(Gas Insulated Bushing), 변압기, 배전반, 케이블, 회전기(모터, 발전기)등의 진동 검출 대상 시설물에 부분방전이 발생하거나 부분방전으로 인한 결함이 발생하는 경우 부분방전/결함의 이상 신호를 검출하는 MEMS 가속도센서가 내장된 다수의 부분방전/결함 검출장치를 GIS관 등 진동 검출 대상 시설물의 외면에 간단히 부착하여, MEMS 가속도센서가 시설물에 발생하는 진동의 크기 및 진동 발생의 순위를 판단하여 부분방전/결함의 발생 위치를 정확하게 검출함으로써 부분방전/결함으로 인한 전기시설물에 대한 2차 사고를 방지할 수 있는 MEMS 가속도센서 기반 부분방전/결함 위치 검출 방법 및 검출시스템에 관한 것이다.
