APPLICATION OF THYRISTORS IN RAILWAY TECHNOLOGY: CONSEQUENCES AND REMEDIES. TESTS TO COMPARE THYRISTOR- CONTROLLED TRACTIVE UNITS FOR 16 2/3 HZ ON THE SAME TEST TRACK
This report covers the results of comparative measurements which, in 1970 and 1971, were taken with thyristor- controlled locomotives of different administrations (181 series of the DB, Rc 2 of the SJ and Re 4/4 of the BLS) on the systems of the German Federal Railway and the Swedish State Railways. The object of these investigations was to ascertain whether it would be possible to explain the different results of tests as being due to the various supply systems, as previous studies of UIC Study Group 5/A/22 gave reasons to assume. The comparative measurements showed that, with the exception of the one overhead contact system on the test track of the SJ which was fed from one side only, the connection for feeding the overhead contract system did not exert an appreciable effect on the magnitude of the interfering current. The difference between the interfering currents of the three locomotives was mainly due to the varied stray reactions of the transformers.
