Application of numerical simulations for improvement of line lightning protection device efficiency

Abstract

In this paper we report on recent progress in application of numerical modeling for development of Line Lightning Protection Devices. The ability of previously developed arc model to predict the current interruption capability of certain LLPD designs is demonstrated on real LLPD prototypes tested in high-voltage laboratory. As a case of particular design improvement we describe the calculation of optimal value of LLPD additional chamber volume.
