Abstract :
A measurement method of very-fast-voltage rise curves due to gap discharge using the coupled transmission lines was examined to discuss a electromagnetic noise source from a viewpoint of electromagnetic compatibility (EMC). The measurement system consists of a distributed constant line system, because the voltage transients were very rapid. A characteristic of the gap electrode, which has a matched impedance for the distributed constant line system, was investigated in the frequency range below 5 GHz. The voltages of power source in experiment were 510 V and 800 V because the Paschen´s law holds stability in air condition. As a consequence of the experiment with this measurement system, the measurement method made it possible to observe the very fast rise curves of about 100 ps
