Abstract :
Correctly estimated the number of partial discharge (PD) source is the premise of the power transformer PD location based on ultrasonic array sensors. Therefore, estimation of the number of power transformer PD source is a very necessary research work. In this paper, we proposed the modified canonical correlation technique (CCT) to estimate the number of transformer PD source. The simulation experiment results confirm the validity of the method.
