APPLICATION OF THYRISTORS IN RAILWAY TECHNOLOGY: CONSEQUENCES AND REMEDIES. SIGNAL INSTALLATION INTERFERENCE FROM THE OPERATION OF THYRISTOR CONTROLLED TRACTION VEHICLES ON THE CSD RAILWAY SYSTEM

Interference in track circuits by thyristor controlled traction vehicles (for 25 kV/50 Hz) was investigated by CSD during 1970/1971. Measurements of 25 Hz, 75 Hz and 275 Hz track circuits did not produce any values exceeding the permissible limits. For 400 Hz track circuits, however, unacceptably high interference values were determined. Of the three different traction vehicles used thyristor controlled electric trainset SM 488.00 caused the greatest interference.
