Step-by-Step Protection of a Wind Turbine with LV Surge Arresters

Wind turbines are systems frequently exposed to lightning and surge impulses. In the protection of these systems, not only external lightning protection systems but also LV surge arrester systems should be used.

Accordingly, we can arrange the LV surge arrester placement in a cascaded manner as follows.

The parameters of the surge arresters to be used are determined by performing a lightning risk analysis. Another important issue is the operating voltage and grid type of the surge arresters to be selected. You can read this article to get more detailed information about surge arrester selection.
