Study of Thermal Behavior of Porcelain Insulators with the Finite Element Method
In order to study the thermal behavior of the distribution line porcelain insulators when the line’s conductor current is high, a laboratory condition in a simulation program (ANSYS) was created considering the structure and geometry of porcelain insulator based on finite element analysis and working out distribution maps of temperature changes. The numerical results obtained using analytical models are in accordance with data resulting from laboratory tests carried out for this purpose. Remarkable temperature rise was not observed at insulators in spite of the high conductor temperature.
