| Abstract: | 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. |
