Copper-Electrode Voltage Falls and Electric Fields of a 540 VDC Free Burning Arc in Air: Dependence on Pressure and the Application to the More Electric Aircraft Issue

With the increase in DC voltage levels in aircraft electrical networks up to 540 VDC, it is essential to improve the understanding and characterization of fault arcs. This article focuses on the characterization of opening electric arcs in air, between 100 and 1000 hPa, through static electrical quantities, namely the...

Analysis Of Particle Contamination In Gas Insulated Busducts Operating On High AC Voltages

The high reliability and safety provided by the compressed gas insulated substations(CGIS) has proved that the they are more advantageous than the conventional air insulated substations. All the parts of the GIS are enclosed in metal enclosures which are filled with SF6gas, which has higher breakdown strength than air....

Effect of Metallization Corner Radius on Electric Field Distribution, Partial Discharges and Breakdown Voltage

Sharp edges and corners of conductive patterns on dielectric substrates locally intensify the electric field, which is a primary source of partial discharges (PD) in high-voltage electronics. This study investigates the in-plane edge radius of a conductive path as a critical design parameter governing PD inception. Ste...
