Abstract
A test terminal for a lightning arrestor in an electric power transmission system is formed of a unitary generally cylindrical ceramic element having metallic end caps secured thereto. A bar-shaped electrical bypass conductor is removably secured to the end caps. An electrically conductive glaze is applied to the external surface of the ceramic element along a band between the end caps, and spaced apart therefrom. The electrically conductive glaze serves as a guard electrode for attachment thereto of a clamp of a test lead. The cross-sectional area of the conductor is less than approximately 5% of the mean cross-sectional area of the ceramic element.
