Gas discharge arrester

摘要

A gas discharge arrester in which annular bands are attached to the inside surface of the arrester. The spacing between the bands is equal to or somewhat greater than the width of the interelectrode gap. Each band is in contact with its associated electrode. The bands function to minimize the effect that placing the arrester in a metallic cup has on the symmetry of the electric field in the arrester, and, at the same time, act to lower the impulse breakdown of the arrester.
