Hydrophobicity Class of Porcelain Insulators Base on Information Image Feature Extraction Via Image Processing
Nowadays, quality assurance of polymeric outdoor insulators service life is necessary to be checked regularly for use, the hydrophobicity is usually a laborious parameter to determine in this field. Regarding this purpose, image processing by classification by followed the standard IEC TS 62073-2016 from photography on wet areas around insulator surfaces has been the main technique. This paper is the study and construction of a test kit about the effect of hydrophobic levels of insulators. There is testing with the 52-1 porcelain insulator with RTV coating. Here we show that the result of the level of hydrophobic with levels from HC1 – HC7. Moreover, the image processing applications enable to quantify and relate these properties in a mathematical function were found, that could be used in the field by the electrical companies because no human errors are detected and can add conditions to improve algorithm.
