During a study of the indirect effects of lightning discharges on wires of a rotorcraft performed as part of AFARP 17 (Anglo French Aeronautical Research Program Nb 17), it has been necessary to simulate the various parameters of a real lightning stroke (E, dE/dt, l, dl/dt). In this objective, three different methods have been used: High current pulse injection, low level C.W. current injection and high voltage arc coupling. In the first part of this paper, we present a short description of the experimental set up and we analyse the data recorded during each experiment. In the second part, we present the method used in order to determine the participation level of each component of the aggression (l, dl/dt, dE/dt) and we expose why it is very important to take the dE/dt component into consideration.
