DEVELOPMENT OF A NEW VOLTAGE CUT-OUT FOR D.C. CURRENT LINES ON THE NS

NEUENTWICKLUNG EINER SPANNUNGSSICHERUNG FUER GLEICHSTROMBAHNEN DER NIEDERLAENDISCHEN EISENBAHNEN

Railway signalling systems use the rails for transmitting information and for detection. Difficulties obviously arise in that rails are used for conducting electric traction current. Because of return currents and the possibility of short circuits with the contact wire, unacceptable differences in potential may occur between ground wires and rails. To protect against this, voltage cut-outs are fitted. The authors describe cut-outs that meet NS requirements and give details of test and operational results.
