COMPATIBILITY OF SIGNALING WITH A.C. PHASE CONTROLLED MOTIVE POWER

This paper describes the basic considerations regarding interference susceptibility of both wayside and trainborn signaling systems. The fundamental mechanisms which cause noise signals to be coupled from the traction power system to the signaling systems are defined with particular emphasis on the effects of harmonics of traction power. The behaviour of the signaling systems is considered for both normal and abnormal conditions. Finally, the entire subject will be calibrated using quantitative data obtained from a series of tests using an E60CP locomotive in actual operation.
