SOLUTION OF TEMPERATURE FIELDS IN METAL OXIDE SURGE ARRESTERS

Martin Gabriš - Bystrík Dolník

   Thermal processes in metal oxide arresters were subject of research. A mathematical model of current and thermal flows was proposed and computed using the finite-element method. Computations were performed for arresters used for 22kV voltage distribution network at voltage levels of normal operation and ground fault.

Keywords: metal oxide surge arrester, thermal stress
