A campaign of measurements on some of the RAΓs rebroadcasting stations of typical design has made it possible to determine the principal characteristics of the over voltages of atmospheric origin that affect stations, as well as the places where they assume dangerous values. It thus became practicable to determine which, in principle, are the optimum precautions to be taken at stations of that type, to reduce the over voltages to tolerable values. Individual tests are, however, necessary for those stations that are particularly endangered by lightning flashes, or that are exceptional on account of the importance of the service or of the complexity of the circuitry.
