Abstract
Starting from a predefined 8/20 µs impulse current, the design and construction of an impulse current source is derived. In the first step an equivalent circuit is defined that meets exactly the predefined impulse current. In the next step the components that are required to realise the equivalent circuit diagram are chosen and modelled by their equivalent circuit diagrams. As far as the components do not show ideal behaviour, the stray parameters if the components are determined by calculation and measurement. Further on, the construction parameters for the geometric structure of the plant are derived from the equivalent circuit diagram of the entire impulse generating network. Finally it is shown that the measured current of the realised impulse current generator meets exactly the desired predefined impulse current.
