Lightning Surge Test Circuit Design Method for Telecommunication Equipment

Abstract

This paper proposes a lightning surge test circuit for estimating the resistibility of equipment against lightning surges. Lightning surge voltages appear on telecommunication lines and reach terminal equipment and can cause significant damage. A simple lightning surge test circuit composed of a small number of circuit elements is proposed. The circuit element design method simulates lightning surge fed into equipment. A circuit design example is shown and it is shown that the simulating error is less than 30%.
