Signal Processing of On-Line Locating PD in Transformer

Li Can and Lou Zhangda Southeast University, Nanjing 210096  
An ultrasonic signal processing method of on-line locating PD in transformer is described in this paper. It can detect ultrasonic signal sensitively and the result of time delay estimation is satisfactory. A method to determine the relation between electrical signal and ultrasonic signal of the on-line locating is also supplied.
