Kinerja bahan isolasi non keramik di daerah tropis by Perpustakaan UGM, i-lib

“…Part of specimens is coating by silicon compound Experimental method was carried out through the following procedure : (I) the contaminant coating on specimen surface in fog chamber and simulation of ultra violet radiation, (2) the ac voltage was applied between two electrodes inserted into specimen surface, (3) the measurement of leakage current on contamination specimens surface, and (4) the calculation of equivalent salt deposit density (esdd) On the basis of the results, it can be concluded the increase both esdd and uv radiation on the specimens surface cause the increase of leakage current. …”
