Abstract
A high-voltage system surge eliminator for the protection of electric transmission and distribution stations against line and switching transients, atmospheric discharges and other adverse effects including such as those caused by lightning. The eliminator is suitable for the protection of substations and of individual equipment units, selectively, and is applicable to both direct current and alternating current single and multi-phase systems, selectively. Two basic and typical eliminator varieties are shown and described.
