Compare different recent methods and propose improved method for risk assessment of damages due to lightning

Abstract

This paper compares and analyzes the different methods of risk assessment of damages due to lightning in IEC 62305-2 and AS/ANZ 1768 standards. From there, proposes the improved method based on the calculation method recommended by IEC 62305-2 standard, with some additional and more detailed calculation formulas proposed by AS/ANZ 1768 standard and the shielding factors along the distribution line proposed by IEEE 1410 standard. The LIRISAS program for calculating the risk of damages due to lightning is built on the proposed method, has the reliable result, high accuracy and the user utility.
