Analysis of the Characteristics of Partial discharge in a Cable splice using a Ultrasonic sensor
초음파 센서를 이용한 케이블 접속재내 부분방전 특성분석
Abstract
This paper describes the study on the basic characteristics of discharge generated in cable splices using ultrasonic measurement method. Two kinds of defect which might be existed in a real cable splice were simulated. One is surface discharge moisture and metallic alien substances and the other is partial discharge by metallic particle. As a result, there were some differences in the characteristics of ultrasonic signals according to each defect. Therefore, it was found that is could be possible to protect the failure in cable splices in advance by analyzing the ultrasonic signals coming from the cable splice due to partial discharge.
