Breakdown behaviour with respect to the impact of technological failures in synthetic air insulated systems_report 2019_part A

Popis výsledku v původním jazyce

In previous research co-operation between SE and ZCU numerous tests have been performed to describe and predict the dielectric breakdown behavior in synthetic air gas insulation between generic geometries representative for ideal medium voltage switchgear design elements. The investigations were focused on discharge gaps of up to 150 mm, gas pressure up to 3.5 bar (absolute), lightning impulse voltage and 50 Hz AC voltage waveforms. Especially the configurations at strong inhomogeneous field and limiting homogeneity respectively had been studied. Concerning the practical industrial manufacturing of GIS one next step in research was performed, to investigate the impact of defects like protrusions caused by technological imperfects. The obtained results should be valuable for proper designed GIS equipment in manufacturing and quality testing. In the given report the obtained results at lightning impulse stress voltage will be described.
