Abstract – In this work an extensive analysis of the impulse current generator at the high-voltage department of the. TU-Graz was carried out. The aim of this work is to generate a detailed equivalent circuit for this test generator. From measured impulse currents and respective charging voltages the surge circuit elements of

sioning, they are therefore tested for reliability with standard impulse voltages or impulse currents. Depending on the apparatus and the type of their proposed K. Schon, High Impulse Voltage and Current Measurement Techniques, . lightning impulse voltage generator with which the waveform is obtained need not.
An impulse generator is an electrical apparatus which produces very short high-voltage or high-current surges. Such devices can be classified into two types: impulse voltage generators and impulse current generators. High impulse voltages are used to test the strength of electric power equipment against lightning and
Abstract: - This paper presents an analytical method for the design and analysis of impulse current generators according to the requierements of the international standard IEC 60060-1. The circuit of the generator is analyzed and mathematical expressions for the most important circuit and impulse current parameters are.
