Abstract
This study presents the experimental results of a newclean and three naturally geothermal polluted porcelain insulators. The experimentals were LC and applied high voltage measurements used a two-channel storage digital oscilloscope, in the hermetically sealed chamber, where temperature, humidity, pressure and applied voltage could be adjusted and measured simultaneously. The LC waveforms were analyzed using FFT and the statistics concerns were analyzed using FMCD of robust multivariate statistical tools. Furthermore, the data were made correlations using CCA. The LCs were significantly influenced by RH. Otherwise, very small data were suspected as outliers, and the dependent variables were linearly function to independent variables, based on CCA.
