Abstract: The contamination seriousness level in the working condition of transformers turns into the most critical factor in deciding the protection level of bushings. Flashover because of contamination on bushings makes a noteworthy danger the unwavering quality of the transformers and power framework arrange as well. In order to reduce the pollution flashover of bushings, the silicon grease coating is applied on the surface of bushings. Then, silicon grease coated and non-coated the bushings are polluted with Nacl and Kaolin blend using brushing method. After dried, breakdown voltage of polluted bushings is measured as per standard and the statistical analysis has been carried out to understand the performance of bushings under polluted environment.
Keywords: Bushings, Breakdown Voltage, Silicon Grease Coating, Pollution and Statistical Analysis.
Scope of the Article: Predictive Analysis
