An experimental investigation was performed on UHV tower model for the EMTP multiconductor calculation or lightning overvoltage at substations associated with back-flashover at an adjacent transmission tower. The various lightning surge response characteristics were measured on an actual UHV tower, and parameters of a multistory transmission tower model that can reproduce voltages across the insulator strings, voltages of the crossarms, and voltages of the power lines were determined. A value of 120 {Omega} was determined as the surge Impedance at each section or the multistory tower model, which closely agreed with the tower surge Impedance measured for the UHV tower alone.
