There you go, folks. Where a distribution line "deadends," you may see two or three insulators that look similar to bells, and in a string. Where these fit together is a possible source of RFI as the mechanical tongue-and-slot fittings build up oxide. The capacitance across the string of bells causes the gaps to spark over 120 times a second: RFI! Current practice is to replace these "bells" with a unitary polymer plastic insulator that has corrugations, or "sheds." Much cheaper and stronger than porcelain strings, and they DON'T CAUSE R-F-I. So things are working toward less RFI off distribution lines, believe it or not. In Powell's case, Georgia Power/Entergy (or whoever) will probably replace all the old bells with the new polymers. 400-Hz Charles Charles A Taylor, WD4INP Greenville, North Carolina _______________________________________________ IRCA mailing list [email protected] http://montreal.kotalampi.com/mailman/listinfo/irca Opinions expressed in messages on this mailing list are those of the original contributors and do not necessarily reflect the opinion of the IRCA, its editors, publishing staff, or officers For more information: http://www.ircaonline.org To Post a message: [email protected]
