The Electric Impulse Technology (EIT) is being researched in several projects at the Endowed Chair for Construction Machinery for different areas of application. High-voltage pulses are generated using a multi-stage pulse voltage generator. Each stage consists of capacitors which are charged in parallel to a low high voltage via a DC voltage and connected in series via spark gaps, so that a high pulse voltage is created. In order to be able to guarantee a smooth and trouble-free operation of the system, a staggered ignition of the spark gaps is necessary, since otherwise components are overloaded or the necessary pulse parameters are not achieved.
With the help of fiber optic cables, the light signals of the spark gaps should be transmitted to a detector during operation and monitored with regard to the firing order and misfiring. For this, a precise measurement of very short times (nanoseconds) has to be realized.
