Method for detecting the position of a wave front in a signal received by a detector

摘要

The method involves converting a signal received by a detector into a digital signal, defining a working group of N successive samples in the digital signal, and processing the samples. A root mean-square value of the energy of the signal is calculated on a sliding window comprising an optimal number of samples less than the successive samples, from the processed samples. The position of a wave front corresponding to that of the sample for which the energy of the signal exceeds a threshold (D) is determined. Independent claims are also included for the following: (1) a method for determining the response time of a detector exposed to an acoustic signal (2) a method for detecting and locating a partial discharge source in an electrical apparatus placed in an enclosure containing an acoustically conducting fluid.
