Abstract :
This paper describes a diagnostic technique of cable splice by detection of ultrasonic signal. For simulating the ultrasonic signal by partial discharge, an ultrasonic generator was inserted in cable splice. Internal defects were purposely made by needle electrode and ring shape electrode in cable splice. It was shown that defects in cable splice can be detected and the position of defects would be found out by ultrasonic signal measurement
