Abstract

The paper deals with the problem of behaviour of 25  kV,  50  Hz  supply  system  at  Czech  Railways.  Traction  supply system is represented by contractor supply line 110 kV, supply  substation  and  contact  line.  The  main  problem  is  short-circuits  at  contact  lines.  These  effects  can  arise  during  failure  states of traction circuit. It is necessary to know exact behaviour of traction circuit for adjusting of operation protections.
