Pulsed discharges in water are investigated to obtain knowledge of fundamental aspects of their behavior. The electrical energy dissipated in one pulse is measured with a calorimetric method to be 80 mJ. From photographs detailed information on strea

Partial discharge (PD) measurements are an important tool to assess the condition of the insulation of high-voltage systems. Preferably, these measurements are done on-line during regular operation. This paper gives an overview of developments and ex

The authors use a physical arc model to compare the switching behaviors of circuit breakers in a direct and two synthetic test circuits with a computer program. It was found that not only the shape of the transient recovery voltage, but also the topo

The formation of streamers in a 25-mm gap in air is studied with an intensified charge coupled device camera with high resolution in space and time. Strong branching is observed and streamers reach the cathode in an area that is much wider than the g
