Investigation of Surface Modifications in ADSS Cables Due to Dry Band Arcing

In the present work dry band arcing phenomena on ADS'S (All-dielectric-self-supporting) cables has been studied using chemical analysis. To determine the degradation level and behavior after IEEE 1222 Electrical surface degradation test, several test methods, such as Oxidative Induction time (OIT)/ Differential Scanning Calorimetry (DSc), Thermogravametric Analysis (TGA), Fourier Transform Infrared Spectroscopy (FTIR) and Scanning Electron Microscope (SEM) analysis were used. The results of these physico- chemical analysis reveal that, dry band arcing IEEE 1222 test standard is a surface degradation lest method which only effect the sample surface get carbonized.
