On the Discharging Character of Aluminium and Oxide-film Lightning Arresters

Abstract

In this paper, the studying results of behavours of the Aluminium cell and the Oxide film lightning arresters for the audio frequency E. M. F. are a Braun tube oscillograph is used for this studies.
It is stated in this paper that the Aluminium cell is superior, as a lightning arrester, to the Oxide film, because the former has no falling character in its discharging characteristic and large condenser action and moreover its discharge is not so suddenly as that of Oxide film, so that it produces no electric oscillation in the electric circuit by its discharging actions, while the latter has small condenser action and sudden discharging character, so that it has ability of bringing about the electric oscillation. The experimental result shows above facts.
