Abstract EN
High voltage condenser bushing is one of the important component that is widely used in the high voltage system.
At high voltage levels more than 52kV the distribution of electric field in condenser bushing is irregular between the lead conductor and the grounded metallic flange.
This paper studied the effects of changing in both: the number layers of aluminum foils and Oil impregnated Paper (OIP), increasing the length of aluminum foils layers, and also increasing the thickness of OIP layer on the distribution of electric potential and electric field in condenser bushing by using Finite Element Method (FEM) and built the bushing model in ANSYS software.
The harmonic analysis was performed of the bushing model at maximum value of withstand voltage test at 50Hz, from the analysis results are obtained the maximum value of electric field on the inner and outer surface of the bushing, the obtained electric field values were good and acceptable compared to the permissible electrical stress values of the dielectric insulators.
This work can also aid in the design of high voltage bushing stress control, a knowledge of the electrical field distribution in bushing geometry.
Moreover the results of analysis are shown as contour plots, graphs plotted, and High voltage condenser bushing is one of the important component that is widely used in the high voltage system.
