| Summary: | XLPE insulator cable has been widely used underground due to urbanization and this has exposed cable to many pollutants. Existence of pollutant on cable layer may mitigate performance of cable especially on XLPE insulator. Many studies had been done to identify effects of pollutant towards XLPE insulator performance and has showed various results on it. However, effect of mineral layer on space charge on underground XLPE insulator remain unanswered. These minerals Silicone Dioxide, Titanium Dioxide and Aluminium Oxide exist due to its content in underground soil. The purpose of this study is to determine space charge effects towards contaminated XLPE insulator with these contaminants forming a uniform layer on cable. Space charge density gives a view on performance of XLPE as insulator as its existence may shorten life span of cable. Result has shown that these uniform mineral layer reduce space charge density effects in XLPE insulator and this has improved its performance. Besides than taking study for different contaminant, each contaminant is being tested on its different thickness on cable at 1mm, 2mm and 3mm. Consequently, relationship of thickness contamination layer with space charge density is established such that it is random. Al2O3 has shown the least space charge density presence when it contaminates the cable. Decrement of space charge gives a view that these minerals can be used as nanofillers at optimum sizes. |
