Simulation of transformer behaviour subject to fast transients using a tesla transformer

The main purpose of this project is to investigate the stresses caused by the external disturbances and to suggest possible design improvements. To investigate the effect of those HF pulses a complete test system has been developed. This test system has the possibility to simulate the measured HF pulses and to add them to the 50 Hz mains waveform. After applying a series of HF pulses to the test object, the possible degradation of the insulation is checked by measuring the partial discharges (PD) and the voltage level at which they occur
