Interaction of electromagnetic fields generated by lightning with overhead electrical networks
In this chapter, we will present the theory describing the interaction of lightning electromagnetic fields with overhead lines, with particular reference to power systems. In the first part of the chapter, we will present the different approaches and formulations that can be used to describe the coupling between an external electromagnetic field and a transmission line. Then, we will extend the selected field-to-transmission line coupling model to include the effects of a lossy earth serving as a return conductor and to deal with the case of multiconductor lines. The time-domain representation of coupling equations, useful for analysing nonlinearities, will also be dealt with.
