SIMULATION OF CURRENT INTERRUPTION AND POSSIBILITIES OF PROTECTION OF PHOTOVOLTAIC SOURCES

Ľudovít Hüttner – Igor Kertész – Martin Liška

   This article describes the importance of simulating the behaviour of current interruption. In the last years, computer simulation has obtained a significant position in the investigation and development of technical products and in the area of electrical devices. The results of simulation are presented of short-circuit current interruption for a miniature circuit breaker (MCB) and of interruption of the follow current in a lightning arrester with a spark-gap. The article treats also the issues of DC current interruption with switches and the behaviour of electrical devices during passage of impulse currents.

Keywords: simulation, short-circuits current, MCB, overvoltage protection, surge arrester, follow current, arcing chamber
