G.. 3300 Volt Station Arrester 2500 Volt Pole Arrester, Wooden Cover, Lid Removed Arc Circuit types of Garton-Daniel> lightning arresters are u>cd at the sta-tion, usually in connection with choke coil-, apd at intervals of about one-halt mile on the line. So installed, they afford adequate protection to both arc lamp- and to gen-erating or transforming apparatus. A low resistance is used in these arc arresters in series with a small air. ap. The resistance serves to eliminate disturbances which would otherwiseoccur on the circuit at the time of a discharge and assists materially in ex-tinguishing the flow of line current following the discharge to ground. Station arresters are furnished in standard polished and lacquered finish.Pole arresters are furnished with wood covers as illustrated. • Choke Coil No. 50042, listed on page 51, i> recommended for use on arccircuits of 10 amperes or less.
