| Abstract: | This paper concerns the suppression of very fast transient overvoltages(VFTO)in gas insulated substations(GIS)by putting magnetic rings on the GIS busbar. High voltage simulation tests were performed on the magnetic rings of three kind materials, i.e. ferrite, amorphous and microcrystalline and metallic magnetic powder core. Special attentions were paid on the influence of magnetic saturation. The tests showed that under proper parameter coordination magnetic rings could effectively decrease the VFTO amplitude and steepness. |
