Özet:

 

Epoxy resins have excellent mechanical and electrical properties; thus, they are commonly preferred in the  electrical{electronic sector as insulation materials. These insulation materials experience degradation such as breakdown,  tracking, or treeing. Therefore, safety and reliability tests of insulation materials have great importance in estimating  the performance of insulation. These tests must be carried out to decrease the risk of electrical insulation fault. In  this study, the relationship between tracking failures and the data obtained during experiments was evaluated. Tracking  failure performance of epoxy resin was investigated using the IEC 60112 test standard, which is known as the comparative  tracking index test. Leakage current data, collected from the experimental setup recorded from a ground electrode, were  decomposed by using the Fourier transform method. The 3rd, 5th, and 7th harmonic distortion components of the leakage  current data were calculated and their relationship with the number of drops falling on the sample was interpreted. Then  the harmonic distortion components relationship was explained under dirty and clean surface conditions. We explained  the tracking pattern formed on the surfaces of the samples after completion of the experiments was decomposed using  image processing techniques. The capacity, information, and correlation dimensions of the resulting tracking patterns  were calculated using fractal dimension analysis. Shapes in the same terms were examined using fractal dimension  analysis.
