Abstract:
An analyze is made of the limitations of the related parameters in the calculation formulas of ground flash density, and a more reasonable method by calculating of the risk component of lightning disasters is presented. Based on the mathematical model of lightning strikes and the probability distribution of lightning current amplitude, the limitations of the calculation method for the equivalent area in GB50057-1994 and IEC 62305 are discussed, and a new method is given.
