Impulse Voltage Distribution in Countershielded Disc VS Interleaved Disc Windings on 500 kV Power Transformer Design

Moh. Slamet Wahyudi, Rudy Setiabudy
Abstract—Interleaving and countershielding are known as two methods which are commonly used to increase the winding series capacitance. Countershielding has been proven as an effective way to substitute the interleaving as it can be faster and easier to manufacture. The aim of this paper is to find out the most optimum configuration in terms of cost and design by referring to the calculation result of the impulse voltage distribution obtained by interleaved and countershielded winding. A numerical and finite element method (FEM) are used for calculating the series capacitance values as well the voltage distribution along the winding. The result shows that combination of single and double countershielded disc configuration provides an improved impulse voltage distribution and lower voltage stresses compared to the other configuration.

Index Terms—Impulse voltage distribution, interleaved, countershielded, disc winding, capacitance.
