In the latest issue of the magazine Przegląd Elektrotechniczny an article entitled Measurements of the trajectory of a long spark in three-dimensional space was published which was co-authored by an employee of the High Voltage Department Msc Michał Molas.
The article presents aspects related to laboratory measurements of a long spark trajectory for lightning and switching strokes with positive and negative polarity. The paper presents an experimental setup that enables long spark measurements in conventional sphere-plate and sphere- sphere high-voltage systems, as well as in model systems reflecting the phenomenon of a discharge along the insulator chain. The described method can also be used to conduct measurements in multi-electrode systems. The presented measuring system and the method of long spark measurements make it feasible to determine the parameters of the discharge trajectory, which can be used to develop and validate the simulation models of spark discharges with the use of fractal modelling.
