Secondary Fast Breakdown in Narrow Bipolar Events

Marcos Rubinstein, Dongshuai Li

The physical mechanism of Narrow bipolar events (NBEs) has been studied for decades but it still holds many mysteries. Recent observations indicate that the fast breakdown discharges that produce NBEs sometimes contain a secondary fast breakdown that propa ...

Field-to-Transmission Line Coupling Models With Special Attention to the Cooray–Rubinstein Approximation

Marcos Rubinstein

There are three equivalent procedures to evaluate the voltages induced by lightning on power lines, namely, the Agrawal–Price–Gurbaxani model, the Taylor–Satterwhite–Harrison model, and the Rachidi model. The Cooray–Rubinstein approximation is a procedure ...

Modeling Current Transients in a Reciprocal Motion Tribocorrosion Experiment

Stefano Mischler, Shoufan Cao

Tribocorrosion of passivating metals is a dynamic phenomenon causing degradation of materials by a combination of mechanical wear and electrochemical dissolution. The mechanical action typically produces a local removal of particles, metal as well as oxide ...
