The principal of operation for ESE Lightning Arrester is to create an upward propagating streamer earlier than conventional air terminals or other objects on the earth by collecting and storing ground charge during the initial phase of a thunderstorm development and emits strong and consistent upwards streamers to intercept leaders.

ESE Lightning Arrester is designed to last for the life time of your building or structure. This would remain true unless local government regulations changed or property alteration or additions were made.
