Some Significant Problems of Lightning Protection in Flexible Energy Systems

The lightning protection of different components of flexible systems are more and more important because the produced energy quotient increases by the time. Proportionally, the risk and the number of the lightning strikes and the probability of the fault are increasing, too. Nowadays the renewable power plants take a determinative part in the energy sector and therefore, it is necessary to calculate with the loss after a lightning strike or because other overvoltage caused fault.
