Identification and analysis of partial discharges by means of acoustic emission sensors on insulators type PIN55-5

Abstract

An ANSI 55-5 pin-type insulator called as a test of test, to which tension was applied to several levels, based on the nominal voltage specified by the manufacturer, until the presence of DP was detected through measurement instruments. With the obtaining of the database product of the tests performed, a mathematical processing can be used using MATLAB when applying the correlation of the two signals and by using the Pearson coefficient for the interpretation of the results obtaining a highly significant correlation validating the Proposed method.
