실규모 구조체 모델에서 접지시스템의 뇌격전류 분류율 분석

초록

This paper presents distribution ratio analysis of lightning current using real-scaled earth-termination system model of the structure. The effective schematic of experimental model was taken to simulate current distribution for other conditions, and current distribution were analyzed with two current sources of both AC and impulse. In this result, when the lightning current flows in the earth termination system at the AC source was less than 50 %, the lightning current at the impulse source may more than 50 % .
