Abstract
In this contribution the various behaviors of arc voltage created with extinguishing system and the influenceon current and energy released behavior in the extinction system are theoretically and experimentallyanalyzed. In the area of photovoltaic it represents the increase of working voltages up to 1500 V. Inthe experimental part the oscilogrammes of DC current interruption with various extinction systems arepresented. For the reliability of current interruption mainly in the photovoltaic (PV) networks it is necessaryto dedicate increased attention to development and design of switch and protection gears
