Abstract :
In ultrasonic locating of transformer partial discharge (PD), the key technologies are time-delay (TD) estimation and PD point calculating, which directly determine the correctness and the precision of the results. The TD correlation algorithm has traits of convenient implementation and high precision. Based on the TD estimation, the hybrid unconstrained optimum method for solving the PD point locating equations realizes the specialties of fast iterative speed, wide convergence field and stable outcomes. Satisfying results are received while the algorithms are applied in the transformer PD point online detecting system.
