THYRISTOR CHOPPER CONTROL AND THE INTRODUCTION OF HARMONIC CURRENTS INTO TRACK CIRCUITS

Covers the practical measurements made by London Transport on the levels of induced current in track circuits produced by conventional and thyristor- (chopper-) type traction equipment on their 4th-rail traction supply system. The method of measurement, the subsequent method of analysis and the implications of the results are described and discussed.
