Silicone rubber incorporated with micro-aluminum trihydrate and varying weight fraction of nano-alumina fillers was fabricated and investigated for its space charge and trap-controlled mobility characteristics upon subjecting it to salt-fog aging. The space charge characteristics were studied by using pulsed electro-acoustics. The accumulation of space charge and its density was found to increase with the number salt fog aging cycles. The space charge decay rate and the trap-controlled mobility of silicone rubber specimens during depoling, have decreased, whereas trap depth has increased with the number of cycles of salt fog aging. After salt fog aging, the 2.5 wt.% nano-alumina added silicone rubber micro-nanocomposites have shown better performance with respect to space charge accumulation and space charge decay rate. The enhancement of electric field during the polarity reversal test has occurred with number of salt fog aging cycles. Its enhancement factor during polarity reversal was found to be lower with 2.5 wt.% nano-alumina added silicone rubber micro-nanocomposites, upon salt fog aging. The enhancement of electric field along with reduction in the trap-controlled mobility was observed with increasing number of salt fog aging cycles. [ABSTRACT FROM AUTHOR] |
