Abstract : Lightning flashes mainly differ in current amplitude, in the transferred charge, and the impulse shapes of the lightning current. A mobile impulse generator has been developed for the simulation of the lightning flash characteristics. The main parameter of this newly developed lightning current simulator is the possibility of simulations the different waveforms of the indirect current effects with one test equipment. It can produce unipolar currents up to 50 kA with a rate of rise of 35 kA/us for at least 1,0 microsec. With the same equipment oscillating current waves can be simulated with peak values up to 120 kA or at frequencies of roughly 40 kHz or few kA at frequencies up to 130 kHz. Furthermore, an optimal combination of test sets is presented to simulate the direct current effects. (Author)
