PL

Omówiono zagadnienia powstawania bardzo szybko zmiennych przepięć w obwodach głównych (VFTO) oraz w osłonach (TEV) rozdzielnic z izolacją gazową (GIS), występujących podczas niektórych operacji łączeniowych wykonywanych łącznikami zainstalowanymi w GIS. Na podstawie danych literaturowych oszacowano poziomy zagrożeń izolacji rozdzielnic wywołane tymi zjawiskami oraz scharakteryzowano środki stosowane przez producentów do ich ograniczania.

EN

In the article there are discussed the appearing of VFTO in main circuit of GIS and transient voltage in their enclosure (TEV) during some switching operations. Based on literature data it was estimated the level of threatening the GIS isolation by these phenomena and characterized countermeasure used by the producers for limiting them.
