Refers to a steel tube or rod installed at the top and bottom of a wire discharge electrode. The purpose of this shroud, approximately 3/8" (9.5mm) outside diameter, is to eliminate the corona discharge opposite the top and bottom termination of the collector plate. The enlarged radius of the shroud would require a higher voltage than required by the wire to initiate a corona tuft. The shrouds usually extend about 4 - 6 inches (102 - 152mm) into the gas passage. Prevention of localized sparkover at these critical points eliminates premature wire failure due to electric erosion.
