The finding of a threshold for discrimination of PD pulses overlays using the method based on an analysis of the sequence of extrema |
O.I. MONOGAROV
In this article the method of distinguishing PD pulses is considered. For this method, the technique was developed to find a threshold when comparing the actual and expected values of the signal at the extremum points. The discrimination technique has been developed on the basis of Bayesian detection criteria, minimizing the average risk of overlap identification error. An example of PD signals computer simulation results were obtained, which showed high efficiency of the developed mathematical and analytical solutions.
Keywords: partial discharges, insulation, discrimination, pulses overlay, optimal detection.
