    Three Electrode Types

    While two electrode arresters have the advantage of being lower priced, the opening in the center electrode of three electrode arresters allows the two gaps of the arrester to share a common gas chamber and sparkover occurs almost simultaneously in both sides of the arrester minimizing the current surge in the protected lines.
