STUDY ON THE LIGHTNING CURRENT DISTRIBUTION IN THE TT SYSTEM
Yanming Li · Gaoya dianqi · 2002
The models of the lightning current,the lightning protection system and the distribution transformer are set up.A method for computing the effects of a direct lightning stroke on the protection system of the building is presented.EMTP is used to perform the necessary calculations.The lightning current distribution is analyzed under different waveform of the injected current,different line impedance,and earthing impedance etc.
