摘要

This study presents a detailed analysis of very fast electromagnetic transients (VFTs) initiated by disconnector switching operations in gas insulated switchgears (GIS). The results of the full-Maxwell electromagnetic simulations performed on real-life GIS geometries along with the modeling details are presented. The verification of the simulation results was performed by comparison against both measurements and circuit-equations-based transient simulations with the aim to quantify the achieved simulations' accuracy. The obtained results show a highly accurate shape and acceptably accurate amplitude prediction of dominant VFT waves in GIS, allowing for better understanding of the VFT phenomenon and a significant reduction of the product development time and prototyping costs.
