Abstract

The subject invention pertains to a method and apparatus for lightning protection. The subject method and apparatus can be utilized to provide lightning protection for a marine vessel, other structures near water, and/or land-based structures. In a specific embodiment of the subject invention, an electrode design for allowing the electric current caused by a lightning strike to be grounded to water can be employed. The subject grounding electrodes can be employed such that the electrodes are not completely immersed in the water during normal operation of the marine vessel. In a specific embodiment of the subject invention, such grounding is not in contact with the water at all. The specific embodiment of the subject electrode is designed to enhance sparking initiation. In a specific embodiment, the subject electrode is designed to be at least partially, and in some embodiments substantially, insulate from the water, such that an area of the electrode used as a spark channel is exposed. In some embodiments, even the spark channel portion is insulated. The subject invention can incorporate an electrode geometry which enhances the local electric field so as to promote a spark connection with the water when sufficient charge accumulates in the lightning protection system. The subject electrode can then be used in place of, or in conjunction with, ground plates.
