Ultrasonic partial discharge detector can discover and locate the partial discharge, and is used widely. Recently more and more ultrasonic sensor and partial discharge detector were produced by different producer. There are so many styles and kinds that detector functions are intermingled. For example, center frequency, frequency range, sensitivity are different widely, making the detect results are highly varied. So it is necessary strongly to standard the calibration technology and start application of ultrasonic partial discharge detector. The paper introduces the method and application for ultrasonic partial discharge detector calibration.
