Název v původním jazyce

Breakdown behaviour of gaseous insulation with synthetic air

Popis výsledku v původním jazyce

The paper deals with basic investigation of AC breakdown behaviour of gaseous insulation with synthetic air at different level of field homogeneity and gas pressure. The measurement was performed at different gas pressure ranging from 0.1 to 0.25 MPa andgap distances from 1 to 10 cm, using two electrode test- sets. The test parameters were chosen in such a way that different field types could be realized. At slight non-uniform electrical field the measured breakdown values shows a reasonable agreementto those values based on the calculation of the streamer criterion by using a relevant approximation formula for the effective ionisation coefficient. The best fit to the measured results was reached by slightly changing the parameters of the approximation formula depending on the gas pressure value. At strong inhomogeneous electrical field the calculated streamer inception voltage corresponds to the partial discharge (PD) inception voltage only. These calculated inception voltage fits t
