The new national standard GB / T 21714.2 has been widely used in lightning risk assessment since 2008 when it was implemented.However,in practical work,some simplification of the standard doesn't make the calculation results accurate enough,especially in the case of description and processing,these disadvantages influence and restrict its scope of application and prospects.Therefore,based on complex buildings with variety of electrical and electronic systems,this paper improves the methods to get the value of loss factor(Lo) from different lines.It provides more detailed basis and algorithms,and gives examples.The results show that the refinement of loss factor about different lines is closer to reality for lightning risk assessment in buildings.
