                                                    Which type of surge arrester for which situation?

                                                    Types of surge arresters

                                                    • T1: only used when LPS is present
                                                    • T2: used systematically.
                                                    • T3: only used in addition to a T2 (as lower discharge capacity), if the loads are more than 30m from the incoming T2 surge arrester

                                                    * LPS (Lightning Protection System) = lightning rod, meshed cage on buildings)
                                                    ** After 30m (between the surge arrester and the loads) lightning wave reflection phenomena appear in the cables.

                                                    The 30 meters rule for installation of surge protection devices
