CO2 is a promising gas for replacement of SF6 in high voltage circuit breakers. The electric breakdown in CO2 and mixtures with C2F4 from PTFE nozzles is, however, still not fully understood. To understand the electric breakdown in CO2 and mixtures w

We have developed an electronic circuit for measuring the slope of the current near the current-zero crossing of an alternating current (dI/dt) and the post-arc current in gas-filled circuit breakers. The dI/dt and the post-arc current are measured i

The prediction and understanding of the erosion process of the Cu/W arcing contacts in high-voltage circuit breakers is important for the improvement of the breaker lifetime. The change of the contact geometry due to erosion is a main factor, which i

CO2 is a promising gas for the replacement of SF6 in high-voltage transmission and distribution networks due to its lower environmental impact. The insulation properties of CO2 are, therefore, of great interest. For this, the properties of streamers

In SF 6 insulated high voltage circuit breakers the dielectric recovery is a crucial phase during the current interruption process. Due to the complexity of the conditions after current zero, there is still little understanding of the relevant proces
