A Study on Fault Detection Method in Underground Cables using the Detecting Electro Magnetic Wave and Acoustic Signal

전자파의 음향신호측정에 의한 지중 케이블의 고장점 검출기법에 관한 연구

This paper presents fault detection in cables. We developed the device for detecting pinpoint location of faults in power cables using acoustic method. The proposed device consists of hardware and software for the fault detection. Using the device, we explain how to detect the pinpoint of faults and introduce that the other method use the time delay between electro-magnetic and acoustic signals for the pinpoint of the faults.
