1. Device for protection against surge voltages, of the type comprising a lightning arrester (10) disposed between a first conductor (12) and earth (11), an inductance (14) connected in series with the first conductor (12) and a capacitor (16) which connects the inductance (14) to earth (11), thus forming a pi-cell, the legs of the pi being constituted by the lightning arrester and the capacitor, the inductance being connected between the lightning arrester and the capacitor, characterized in that the capacitance of the capacitor (16) is equal to the capacitance of the lightning arrester (10). |
