V-t Characteristics
A ceramic tube is sealed at both side by electrodes,
and inside of it is filled up by inert gas. The ceramic
type gas tube arrester has superior characteristics
such as mechanical strength, surge absorption
energy and stability. There are two electrodes type
and three electrodes type.
