| Abstract | This report presents comparative inductive interference data obtained from four U.S. rapid transit systems employing chopper propulsion control, as part of the Rail Transit Electromagnetic Interference/Electromagnetic Compatibility program conducted by the Transportation Systems Center in Cambridge, Massachusetts. Chopper propulsion control is standard at three of the systems: Bay Area Rapid Transit District (BART); Metropolitan Atlanta Rapid Transit Authority (MARTA); and Greater Cleveland Regional Transit Authority (GCRTA). The fourth system, New York City Transit Authority (NYCTA), conducted operational tests of a prototype chopper propulsion system installed in a married pair of R-46 cars. The four propulsion systems were designed and manufactured by four different suppliers. The theory of inductive interference generation in rapid transit signaling systems and discussion of the mechanisms involved, has been presented in an earlier report in this series: Inductive Interference in Rapid Transit Signaling Systems, Volume I: Theory and Background (NTIS Order Number PB 87-114427/AS, Price A03). That report provides the basis for analyzing the supplementary data presented here. Suggested test procedures for observing, recording and analyzing inductive interference signals have been presented in a second report: Inductive Interference in Rapid Transit Signaling, Volume II: Suggested Test Procedures, which has not been entered into the NTIS system at this time. |
