Abstract
Dielectric protective cover for a lightning arrester with an early streamer emission device, wherein the lightening arrester includes an active portion for connection to the early streamer emission device for promoting a triggering of an upward leader from the active portion, a down conductor for connection to ground, and a dielectric portion for mounting the active portion on the down conductor, the active portion being separated from the down conductor by an air space formed as a spark gap through which lightning current will pass from the active portion to the down conductor, the protective cover comprising: a first portion for fastening to the active portion; and a second portion for fastening to the down conductor, wherein the protective cover protects dielectric properties of the spark gap against degradation in an environment of the spark gap, while leaving the active portion exposed to the environment.
