APPLICATION OF THYRISTORS IN RAILWAY TECHNOLOGY: CONSEQUENCES AND REMEDIES. INVESTIGATION OF INTERFERENCE IN TRACK CIRCUITS FROM STATIC CONVERTERS USED FOR ELECTRIC PASSENGER TRAIN HEATING

The present report gives an account of tests made by the German Federal Railways (DB) on the Jugoslav Railways (JZ) route system with the object of investigating whether static converters for 1000 V, 16-2/3 Hz heating supply systems cause interference in track circuits. Measurements were obtained with 6 different single-rail insulated track circuits (a.c. and d.c.) under different earthed rail conditions. In every case and even under the most adverse conditions, which would in practice only rarely be met, misfunctioning of track circuits did not occur. Under certain circumstances described in more detail in the report it may become necessary to use a fundamental frequency of 22 Hz (A) instead of 16-2/3 Hz.
