Gauging of bushing under adulterated condition by applying nitrates and sulphates

Abstract

The adulteration on bushing is tranquil of different actinic element, which threats the firmness of superficial insulation and also infects the interior conductor by carrying a lofty voltage current down a grounded circumvallation. Therefore adulteration pernicious and exploit the bushing. An aim to learn the adulteration condition of bushings which are blighted by nitrates and sulphates such as Ca (NO3)2, KSO4, MgSO4 and CaSO4, unnatural pollution study on three different voltage ratings of bushings were carried out. In that leakage current and arc flash voltage was noted then conductivity has been measured and finally ESDD have been calculated using mathematical formulation, hence the results are compared. Later, by using support vector machine (SVM) the percentage error have been obtained by using gaussian and polynomial kernel function, after that the result have been compared by using hybrid SVM with GA (Genetic algorithm). The fast finding scrutiny conclude that, firstly salt concentration get shoot up then ESDD and conductivity will also get shoot up with dwindle in arc flash voltage and leakage current, comparative analysis babble that hybrid SVM with GA exhibit preferable outcome when compared to SVM.
