Experimental and Analytical Studies on Lightning Surge Characteristics of Ground Mesh

Abstract

Lightning surge characteristics of a ground mesh have influence on electromagnetic transient behaviors in low voltage and control circuits. This paper describes experimental and analytical studies on lightning surge characteristics of a ground mesh. The experimental studies are carried out under various conditions. The experimental parameters considering in this measurement include earth resistances, current injection points and injection current waveforms. These measured results are compared with calculated results based on the theoretical studies by Sunde. A comparison of the measured results with the calculated results shows good agreement.
