A novel de‐noising method based on coherence average for ultrasonic signal of partial discharge in transformer
Abstract Ultrasonic method is widely used for the detection and location of partial discharge (PD) in transformer, however, the measured ultrasonic signal is usually corrupted by noise, and sometimes is even buried by noise entirely. Therefore, the de‐noising of the measured signal is essential. Con...
