The Behaviour of Aluminium Cell Arrester under Radio Frequency E. M. F.

Abstract

It has previously been pointed out that Al-cell arrester reveals some remarkable behaviours under the E. M. F. at audio frequencies. Its behaviour under radio frequency E. M. F, is now studied by mean of the Braun tube oscillograpb.
The dynamic characteristics and the cyclic current diagrams have been obtained for frequencies varying between 100, 000 and 200, 000 cycles per sec., from which the wave shape of the current and the potential against time are deduced.
The superior quality of the Al-cell arrester is that the static capacity of the film is considerably large and that the discharge characteristic is non-disruptive. These superiorities may not be superseded by any other type of arrester, even very probably by the oxide film arrester.
