Thus assuming the geometric model to be applicable, the currents collected by Berger, those collected on chimneys, those collected on towers, etc. should have median currents greater than those to the earth or ground. Thus, conceptually, a
ground level current distribution is needed for use with the geometric model. The first investigation of this phenomenon was performed by Sargent [42]. As a result of his analysis, he suggested a ground level distribution having a median of 12.5 kA and a log standard deviation of 0.72. More recently, Mousa and Srivastava [43] suggested a ground level current distribution having a median of 24 kA and a log standard deviation of 0.72, which has been accepted by the IEEE Substations Committee [39].
