The modelling of high-frequency electromagnetic transients taking place in power systems is at the core of several design and protection functions like insulation coordination and fault location. In this respect, this research activity focuses on the modelling of high-frequency/high-power electromagnetic transients in overhead lines and coaxial cables with the target of developing new protection schemes for modern power systems.
Specific research effort are on two subject:
-
Lightning electromagnetic coupling with power systems.
-
Application of the time-reversal technique to fault location and, in general, disturbances location.
