Simulation and measurement of melting effects on metal sheets caused by direct lightning strikes [PDF]

open access: yes
Direct lightning strikes melt metal parts of various systems, like fuel and propellant tanks of rockets and airplanes, at the point of strike. Responsible for this melting are the impulse current and, if occurring, the long duration current, both ...

Overvoltage propagation from transmission line into transformer winding [PDF]

open access: yes, 2015
The paper deals with very fast transient phenomena in a system consisting of two parts: a cable line and a transformer winding. In this case an adequate model should be considered as a circuit with distributed parameters.
