In order to create an arcing section capable of carrying lightning current with several arcing sections connected in series, the arcing section consisting of n arcing part-sections (FS), whose arc drop voltage is brought to a level of n times the arc drop voltage of one arcing part-section by the series connection of the arcing part-sections (FS), and the arcing part-sections (FS), with the exception of the first arcing section (FS1) to operate in the event of a lightning strike, being wired with capacitances, so that the arcing part-sections (FS) break down successively, the second and every other arcing section (FS2 - FSN) being connected directly to a common reference potential via the capacitances, in such a way that it only fires in the event of an overvoltage due to lightning, it is proposed that the sizing of the control capacitors is carried out in accordance with the following formula:
(n-1) x CE = k x CL x where n is the number of capacitors, CE each control capacitor, k a safety factor 1, CL the capacitance of the conductor from the arcing
section to the source of the overvoltage, the peak value of the overvoltage and Us the protection level of the arcing section.
